Hey yo!

I got a friend who is stumped regarding how to fix a problem that has recently cropped up. He is writing the page (which is pasted below) to act as a collector of names and emails. This is to create a fan list. Currently he had it working where you plop in the info and click submit, and a local file gets the data. Where is the error. I checked it on the w3.org HTML validator and none of the erorrs are relavent to this.
