php4 on win2000 and apache1.3

I'm having trouble installing php on win2000 and apache1.3 It seems to work but only some of the basic functions. If I pass a submit a form and try to grab the variables i get errors "Undefined variable XXXX" (I know these scripts work because they work on a different server) Here's what I've done so far Extracted the PHP zip file to c:\php Added the following dlls to c:\winnt\system32\ php4ts.dll Editied my php.ini file under c:\winnt\ ------------ doc_root= "C:/Program Files/Apache Group/Apache/htdocs" extension_dir = "c:/php/extensions/" I was going to uncomment some of the extension=*.dll entries in php.ini but I got tons of errors when I tried that Added the following to my apache httpd.conf file ----------- ScriptAlias /php/ "C:/php/" AddType application/x-httpd-php .php .phtml Action application/x-httpd-php "/php/php.exe" LoadModule php4_module c:/php/sapi/php4apache.dll Am I missing anything? I've tried looking everywhere for a easy to follow setup for php and apache1.3 for windows but everyone I read is different
