Custom fields (plugin) verification

[raperez]

Hello:
I have this problem, but can't find any logical solution.
I have defined a product "box of burgers", which must contain exactly 10 burgers. There are 12 types of burgers, and all of them can be combined to make a box until the 10 units are complete. So you can have 5 of type 1 and 5 of type 2, 3-3-3-1 or any combination which sums 10. I can have a custom field plugin for each type, but I have no way to control that only 10 are ordered. (or 20 if order is 2 boxes, or 30 if order is 3 boxes and son on)
Anybody can help me?
Thanks in advance.

Hi,

I think that what you need is a product builder. I have used the one built by breakdesigns before (you can find them on Google) it's commercial, but was worth it for me.

Cheers
