Running cgi scripts

Hi Again.
I’m still working on getting the movable type stuff to work and I’m running into a problem. I can’t run the cgi scripts from the web page. I get:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

I can run the script when I ssh to my domain. I can also run a simple perl script from my webpage.
