Hi there, It's an issue of 1-n mapping. We will have to change the way to load 1-n by using join query instead of execute a lot of time. ----------------------------------- I'm a senior software developer who have around 300 completed projects and my account is qualified by this site. My page: https://www.freelancer.com/u/DucNA.html Could you please send (or discuss with) me more detail? I'll check and then will let you know my estimation (time and coding effort) for this project. Thanks & best regards, Duc Nguyen ----------------------------------
