XOOPS Physical Path

I am trying to install to remote web server. Everything goes fine until I get the following message. "XOOPS path check: Script is not inside XOOPS_ROOT_PATH and cannot run." I am letting my newbie side show but I have tried every everything I can think of to set the root path. I have the server root path but I cannot get it to work. I have prefaced it with // the ip address the web address, etc. but to no avail. If anyone can help the newbie discover the obvious I appreciate it. I could not find the answer in the install documentation.

Thanks
