help with php and iis 4

alright...i have iis 4 and php installed...php automtically configured settings for iis 4. i can run .php files fine from my webserver but embedded php code in a .htm file will not run. can anyone help me out? i tried reading through the faqs on the main php website but no luck

i added c:\php to the Path environment variable

i messed around with these settings in php.ini file:
cgi.force_redirect = 0
;cgi.redirect_status_env = ;

tried changing them to:
cgi.force_redirect = 1
cgi.redirect_status_env = Path

...but that didnt seem to make a difference. please help.

nevermind....im an idiot. im going to assume that any file with php code has to have a .php extension, even though it still has html in it.
