Im trying once more. Last developer was not able to answer this.
Its like this :
I got Customers
I got Courses
I got Categories of Courses
When a customer has finished one Course, i need to sell another Course in another Category.
I have Salesforce Group Edition, and i would like to use opportunities for doing this job.
Is this possible?
I will pay $30 for you to tell me how to do this, and if this sounds nice and it would give me a nice workflow i will pay you to set it up.
