WebSite Professional and PHP...

I'm giving this one last try, then I'm leaving the list since nobody seems to want to even give even a "Gee, I don't know"... I'm running O'Reilly WebSite Professional 2.80 on Windows NT 4 Server, and would like to get PHP to work with it. I found directions, and followed them... and WebSite is loading and executing the ISAPI module.... But all I get when I try to run a script more complicated than a basic "hello world" it feeds a blank page, (with the HTML headers, but no end tags) and nothing else. Please, someone, help? I already updated my PHP to 4.3.0... but WebSite Professional 3.1 is too expensive at the moment to consider an upgrade. Thanks in advance for any help.
