I have this ASP script that loads both an xml and xsl file. The purpose is to either transform the xml into HTML or WML.
when i try to load the asp file into the mobile toolkit, i get "An internal gateway error prevents the gateway from fulfilling your request".
I tried to load a separate wml file and that works.
Try this tip:

this will help you turn on the logging in the gateway you're using. It may give some clues as to syntax errors in the WML. I've done some ASP stuff and this has proven to be a good trick to have in my toolbox.
