Your CGI will not compile for a start (missing closing ) after for... Plus you totally miss the point of the error check. The do_something() sub should either return 0 ie false if there was no error or the error message if whatever the hell it is supposed to do fails (just like a system call that returns 0 for OK or the error code). We then print out 'OK' if there was no error message or the error message if there was and error. You should be able to call this script and get either the error message or OK in your browser.

The address you type in to get to this script ie http://mysite.com/cgi-bin/script.pl if the address that the second script need to use. Once you have that working the rest will work fine provided you modify the second script to point at this CGI and don't just blindly paste in the IP address I posted - your server is probably not at http://192.168.0.123/ - this needs to be changed.

#/usr/bin/perl -w
use strict;
use CGI;
my $q = new CGI;

print $q->header();
my $err = do_something();
print $err ? $err : "OK";

sub do_something { 
  if ( 1 + 1 == 2 ) {
     return 0;
  } else {
     return 'An error has occurred 1 + 1 is not equal to 2!'
  }
}
