I've recently run into a problem that is a showstopper for me. Basically none of my "Attribute required for text" fields are validating - people can add the items to their shopping cart without filling in the fields. They used to work, but no longer do and I'm not quite sure what the triggering event was that made them stop working.

My cart can be found here

If I knew what file had the actual validation logic I can try and look through it, but I haven't been able to determine which file it is or what fields I'm looking for.

There are two people on this board I've run across who have the same issue, but I haven't been able to determine what our common element is.

Thanks.
