[FX.php List] Can't get FX.php working under IIS

[Chris Bisgard]

Hello all,
 
Sorry this is such a newbie post, but I am really stuck and can't move
ahead until I figure this out. I'm hoping someone has had a similar
problem and can tell me that I've missed something simple or obvious
here.
 
The problem: When I try to query a FM8 database using FX.php, I get no
data and no error codes.
 
I am running FM8SA on a Windows 2003 server machine, and FX.php is
running on the same server under IIS 6.0. I have confirmed that all of
the following conditions are met:
 
-- I can access my FileMaker data via the web, locally and remotely
-- I can view the raw XML data in a browser
-- I believe PHP is configured correctly, as I can run PHP scripts from
the IIS default wwwroot folder
-- I have confirmed that the filename and layout name for the FM8 file
match what's in my query script
-- The FM8 file in question does contain data (it has 100 records)
-- This isn't exactly relevent to FX.php, but I am able to access the
file in IWP
 
One interesting note is that I still have an old Mac running FM5 with a
couple of files hosted on the web, and I *can* get data from those
databases using FX.php on the Windows 2003/FM8 server. Why would I be
able to access data on a different, older server running FM5, and not
the FM8 data from a file residing on the same server as FX.php? 
 
A little more info... I am using port 591 on the FM8 server instead of
the default port 80, because the FM5 server is using 80. Could that be a
problem? I believe I've accounted for it in server_data.php (I have set
$serverIP = '192.168.0.7' and $webCompanionPort = '591'), and I know
port 591 is working correctly in IIS. As for the query itself, I'm not
doing anything complex at this point; all I'm trying to do is a simple
"show all" function to see if I can get ANY data out of FM8SA.

What am I missing? Pulling my hair out here. If anyone is interested in
seeing my code, I'd be happy to post it, as well as any additional info
or clarification.

Any help or advice will be GREATLY appreciated!

Thanks,
