Asp help please

Does anyone happen to know if there is something wrong with this script?

when ever I go the page associated with it in my browser I get a download prompt, it must be a script error. Here is the url....http://www.yourpagetoday.com/login.asp

and here is the asp script.
Thank you all in advance, I really appreciate the help.
