Please read the instructions of your FTP client. CGI programs are mostly called by a hyperlink from within a HTML page. The values may be created by a HTML form, containing hidden fields, input fields or both of them. There are two ways to pass values to a CGI program, the GET and the POST method. Read the instructions provided with the cgi script.
Good scripts mention the required method in the documentation or as a comment in the script itself.
If you design a HTML form to call the script, you have to pass the method. My Script Doesn't Run. Check it in the admin panel. Normally there is no trailing slash. Check the above points again.
