You might need to set register_globals = On for that module. If you must do that I suggest setting globals = Off overall and only setting it On for this module. .htaccess for Apache.
Also suggest getting the latest version 1.3.4 which fixes a few things including security.
I'm assuming this is about xoopsgallery. Always good to mention the actual module name, version, XOOPS version, server OS, etc.
