try use CGI::Carp qw/fatalsToBrowser/; in your scripts. this will spit errors out to the browser. of course, you should use CGI::Carp in development only. you probably don't want potential black hats to have access to your error reports.

as a side note, you shouldn't quote variables unnecessarially, as in

## DON'T!
@execute = ("gettersubscript.cgi", "$var1", "$var2");

## INSTEAD, DO
@execute = ("gettersubscript.cgi", $var1, $var2);

you may accidentally stringify a variable that shouldn't be stringified, leading to subtle bugs (though probably not your current problem.)
