Hi. Ok, so I have displayed:
[Checkbox] Team 1.jpg (id#: 1)
[Checkbox] Individual 1.jpg (id#: 2)
[Checkbox] Action 1.jpg (id#: 3)
The user chooses 2 of the following 3 selections and clicks Next to go to the next page. What gets passed to the next page is the id#. BUT I want him to choose only the 2 files which start with "team" and "indi". If they don't choose those options, it goes back with an error. So let's say he chooses id #1 and id #3, what would get passed to the next page is 1,3. I figured that I would then query for the name of the image, then grab the first 4 characters of the name. If the result is not "team" or "indi", then throw back the error. Not sure how to do this though. Any ideas?
