Hi,
thank you for your reply.

I’m sorry but I dont understand how your suggestion could help me.

Maybe I don’t have explain my needs very well.
I have one checkbox with four option (a, b, c, d). Normally users can select all of them, I want that they can select only two (for example only “a” and “b”, or “a” and “c” etc…)

Thank you! Now everithing is working

But with this code I see all the listings and not only the ones that have set something on the special offer field. And anyway when I click on this listing it give me the 400 Bad Request message
