Ok, here we go. I'm using the previous form to display lists of categories of checkboxes *breath*.
Here it is: http://www.hftvnetwork.com/ProIn/ I'm having problems getting it to only show the amount of blanks it needs, it looks like it closes the last column div and then outputs even more blanks. Here's the view: http://dpaste.com/hold/65175/ It's a little crazy, but when looking at the page, you understand why. Any ideas on why it can't seem to divide by four correctly?
