can't seem to get it to work!

Let me begin by saying "Great tutorial!" Here's my issue; When i run the files on my computer with Microsoft IIS 5.0, it seems to work fine all the way around, but when i upload the files to my web hosting provider, the files with .htm works but none of the asp files work! All I get in return after I click on submit is a blank page. Please let me know how i can resolve this. Thank you..
