I am in the middle of doing a site for some one and I need to make a form. The last part of the form is where I am running into a problem. As you will see the top part of the form (name, address, ext) is all required fields; however the bottom part (name of room-mates) is optional. And unless I type something in those fields it is going to my error page instead of the credit card page. Please someone show me the error of my ways. Thank you. The page is http://wm.pawdesign.net/index-61.html

What's a required attribute? It's not part of any current HTML specification that I know of.

Also, either change the doctype or get rid of the large amounts of deprecated tags and attributes

having said that, the problem is going to be in the receiving php script.
Forms can only send data to the URL specified in the action attribute. There is no mechanism in a HTTP GET or POST to decide whether the submitted data is valid or not and redirect accordingly.

is it just me or is "PAW" design one of the worst name choice for a design company....

can we see the receiving PHP script please..?

deems it is fine here. how did you get the error?
