windows install fails

Hi, I'm a newbie and probably an idiot, coz I can't install PHP. I've installed Apache 2 on my Win NT4 local machine and got it running. Then I've downloaded PHP and tried to install it. After I follow all the instructions from PHP and edit the config files, I try to restart Apache and it refuses to restart. There is an error box but nothing in the logs. If I then comment out the three added lines in the httpd.config then Apache starts up clean and runs sweet as syrup. I've no idea at all what is going on. Can anyone help me please? thanks Simon cheers Simon Warner Computer Systems Officer * * * PLEASE HELP US RECRUIT VOLUNTEERS * * * We still need volunteers for the Stewarding, Under 5s team, Children's, Hosting and Tent Security teams.
