Why does my html ACTION call merely display and not execute my script?

I need to make an html form ACTION call to a rebol script in order to get the data entered on a form. The problem is that although I am using scripts I took off rebol.com or rebol.org, and I have Windows 2000 IIS setup with a virtual cgi-bin directory, and the form does call the scripts, the call merely displays the text within the scripts even recognizing tags and doesn't execute the scripts with rebol. Does anyone have any suggestions as to why this is not working correctly. According to the books REBOL for Dummies, REBOL User's Guide, and independent HTML Documentation publications, the project is set up correctly. Thankyou, Mike
