Thanks for the response. That makes sense. I do have a question, the version of ubercart that is on the site I am working on is 5.x-1.0-beta1. I have created an attribute with no options (thus a textfield appears for the attribute). However, there is no checking done on that attribute, so if I type in </td></tr></table></div> then it messes the page up quite a bit. I was wondering if there is a way that I can hook in to a product and check the attribute once it is entered so that I can verify it is valid?
