The url you have supplied is local, and so will just pull the file off your D: drive.
you need to
- install a webserver, I'd suggest Apache, but that's cos I like it
- Configure a CGI directory in your webserver
- Copy your script to this directory
- Edit your page so that the link points to the absolute HTTP path to your script
the info above is readily available on-line, however your question indicates a lack of understanding of the HTTP and CGI protocols, you should do a bit of reading to familiarise yourself with these. That said learning by doing is also to be recommended ;)
