Method Not Allowed

I'm trying to get a script working and I get a 405 Method Not Allowed error every time I run the script. I understand this is a apache configuration issue, but I don't know what I need to do to fix this. I'm running RH7.0, Apache 1.3.12 and PHP3 all from RPMs. Thanks. *********************************************************** THIS MESSAGE IS INTENDED ONLY FOR THE USE OF THE INDIVIDUAL OR ENTITY TO WHICH IT IS ADDRESSED AND MAY CONTAIN INFORMATION THAT IS PRIVILEGED, CONFIDENTIAL, AND EXEMPT FROM DISCLOSURE UNDER APPLICABLE LAW.
