Perl runs server-side, not client-side. Therefore, you cannot "run" your Perl scripts in a web browser -- they are run on a web server, and the output is viewed with a web browser. If this is indeed what you mean, then:

1. Make sure your script is executable. In UNIX/Linux, this means the execute bit must be set in the permissions for the user running the web server. Something like 755 is often appropriate. Sorry, not sure what the permissions would look like on Windows.
2. Make sure the HTML header is being printed. If you're not using CGI (which you should be, eventually), you need a script that looks something like:

   #! /usr/bin/perl
   
   print "Content-type: text/html\n\n" ;
   print "<H1>Hello, World!</H1>" ;

3. Make sure your web browser is configured to run CGI scripts. You'll have to RTFM on that one. ;-)
