including a file on another server

[klb]

i am running my main script on one server, but including a file from another server in it.  the problem is that nothing displays when i include the file from the other server (it should display a simple integer).  i have tried include(...) and require_once(....), all to no avail.  can anyone tell me why i can't access this script?  i'm including files on the same server as the main script in the main script and those are working fine.  i'm at a total loss and don't want to have to rewrite everything for the main server as that would require ftping of files and a whole bunch of junk like that.  i'm losing my mind, any help would be greatly appreciated.
