Hi there, I understand the frustration when product variant selections don't sync perfectly, especially with multiple options causing UI and functional breakdowns. Your Shopify theme’s current JavaScript isn’t keeping pace with complex variant combinations, undermining customer experience and sales flow. With extensive Shopify theme development expertise and strong JavaScript skills, I’ll analyze and reconstruct your variant logic to precisely track each selection. I’ll ensure real-time updates across availability, pricing, and dynamic button switching based on your €1,000 price threshold, including seamless third-party app integration without any hacky fixes. Expect a clean, modular, and future-proof solution built for reliability. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. I anticipate completing this within 4 days. Could you share if your theme is custom-built or based on a specific Shopify template, and are there any custom apps beyond the notify-me integration affecting variant logic? Thanks, Asad

Hi, I can rebuild your Shopify variant logic so every option combination correctly resolves the selected variant and instantly updates availability, price, button state, and third-party app triggers. I’ll also refactor the €1,000 price-based button switch to run dynamically on each variant change using Shopify’s native variant JSON—clean, modular, and future-proof with no workarounds. Technical approach: Replace the current logic with a centralized variant resolver tied to option change events, trigger a unified UI update handler (price, availability, buttons, app events), and ensure compatibility with OS 2.0 sections and AJAX cart behavior. Best regards, Ihtsham

Hi, I understand the critical nature of variant handling for your Shopify store, especially with multi-option products affecting availability, pricing, buttons, and third-party apps. I can rebuild the variant-selection logic in your theme so that every change reliably updates the selected variant, dynamically refreshes availability, price, and your price-based “Make a Request” button, and triggers all necessary app integrations. The solution will be clean, maintainable, and future-proof, avoiding temporary workarounds. My approach would involve analyzing the current variant JavaScript, restructuring it with event-driven updates, and ensuring compatibility with your existing theme and apps. Looking forward for your positive response in the chatbox. Best Regards, Arbaz T

@expertshopify

Hi, I’ve reviewed your issue and this is a classic case of broken variant logic when handling multiple option combinations in a Shopify theme. Your current JavaScript works only for single-variant products, so when options change, the selected variant is not detected correctly. That’s why availability, price, Add to Cart / Make a Request buttons, and notify-me apps stop updating properly. I will rebuild the variant logic properly using Shopify’s variant data so the exact selected variant is detected on every option change. All UI elements will update instantly — price, availability, button state, and third-party app events. The €1,000 price-based “Make a Request” button logic will also be made fully dynamic instead of running only on page load. No hacks or temporary fixes clean, maintainable, future-proof JavaScript aligned with Shopify best practices. Timeline: 2–3 days Fixed Price: $150-$200 (depending on theme complexity) If you want this done properly and permanently, I can start right away. Thanks Momin Shopify Partner

Hi I’ll rebuild your Shopify variant logic so the selected variant is detected reliably on every option change and the UI updates instantly without edge-case failures. I’ll fix availability, price updates, Add to Cart vs. Make a Request switching, and ensure your notify-me app hooks fire correctly for multi-option products. Your €1,000 price-based button logic will be moved to run on every variant change, not just page load, so the correct CTA always shows. The solution will be clean and maintainable, using Shopify’s variant data and event flow instead of brittle DOM workarounds. I’ve fixed broken multi-variant logic in production themes where UI desync caused failed carts and app integrations.

This will ensure consistent updates on all related UI elements including availability states, pricing, button states, and third-party app events. My judicious approach to problem-solving will guarantee that all updates happen instantly without the need for page reloads. Furthermore, I understand how important it is for you to have an updated pricing based button switch. To address this need effectively, I will ensure that the logic doesn't just run on page load but dynamically updates based on the selected variant's price to display either an "Add to Cart" or a "Make a Request" button.

@abeerahmed12

I will rebuild your theme’s variant selection logic from the ground up to ensure seamless state management for complex products. My approach replaces fragile, page-load-only scripts with a centralized Event Listener architecture. This system will monitor all option changes (swatches or dropdowns), fetch the specific variant ID object, and trigger a global UI refresh. This ensures that pricing, availability, and the €1,000 "Make a Request" button switch update instantly and accurately on every click. To ensure future-proof stability, I will utilize Shopify's native Liquid-to-JS object mapping, allowing the script to detect price and stock changes without relying on DOM scraping. I will also implement a Custom Event Dispatcher that broadcasts the new variant ID to your third-party "Notify Me" apps, ensuring they sync perfectly. The result will be a clean, modular JavaScript file that remains maintainable through future theme updates. best Regards Abeer Ahmed
