isBlank() is not a predefined function in javascript. With firefox / mozilla you can open the javascript console with the url javascript: and you usually get decent error messages (at least, a lot better than in IE).

Also, it's not realy safe to rely on javascript alone to validate a form. You can read and test input with the CGI module's param() method.

update: and you should print the end_html() at the end of the html, not immediately after the start. :-)
