As you say, you have a cgi form and script that works. Therefor perl5 and the CGI module are probably installed on your server. CGI.pm comes with perl.

As chromatic observes you seem to be missing a semi-colen on your third line. As he suggests, you can confirm this if you run the script outside the CGI environment.

btw, if you are curious as to what  perl -cw yourscript.pldoes you should consult perldoc perlrun

If you do not have perl on your local MS windows machine. You can get it from ActiveState

Sometimes, errors happen when you run your scripts from the server but not when you run them locally. In this case you should look at your  error.log file. This file contains errors that are not sent to the browser. (Ask your local system administrator for help in finding this file)

In your case, your error.log file will probably contain a line something like:

Premature end of script headers

This is because the line:

    print "content-type:text/html\n\n";

... never runs to print the script headers.
