I think the best way to describe this is through a screen capture I took.....
http://members.home.com/cameronbr/screen2.gif
from what I understand, a php file coming up as code normally means that Apache doesn't recognise it as a php file, but I think I referred it properly (see srm.conf in GIF image).. the path i put in matches the folder where php4 is located (middle window on screen cap).
I'm thinking it may be a typo or something.
Thanks for your help everyone.
BTW I'm on windows 98.
