multiple quantities one record

Title

multiple quantities one record

Post

Hi, don't really know how to describe this problem, and as such, I've had some issues trying to search for a solution...

Problem: I have an on line store where customers can request quotes. The issue I have is when a customer wants a quote on 500 / 1000 / 2000 of a particular stock. I had this set up as a radio button, but this ended up in 3 different quote numbers - one for each qty. Using the "check box" the customer can now choose all three quantities (same quote no) but I don't know how to extract the different quantities...

Added to this is that the filed is global and gets exported to another table.... any help would be appreciated...   

Regards

Andreas
