>  It looks as though you are trying to include a perl script in the actual
 >  html page - as far as I know, you cannot do this - you need to call the
 >  form.pl (or whatever the file is called).

 >  For example, include in your index.shtml page:
 >  <iframe src=http://www.rocketturd.com/cgi-bin/form.pl FRAMEBORDER="0"
 >  WIDTH="100%" HEIGHT="65"><i/frame>

Any URL you can put in an Iframe, you can just type directly in the address 
bar of your browser.

If the .shtml file is really a perl script, you need to (probably) rename 
it to (filename).pl, and put it in your cgi-bin directory.

If you rename it to form.pl and move it to /cgi-bin, then this URL will work:
http://www.rocketturd.com/cgi-bin/form.pl

If you are doing SSI (Server-Side Includes) as someone else mentioned, then 
provide more details of how you are pulling in your perl script.
