Fatal Error: call to undefined function SetDBData()

[jrough]

Hi, sorry I'm having trouble getting this going. 
I'm getting this error "undefined function":
"Fatal error: Call to undefined function SetDBData() in /Library/WebServer/Documents/fmquery.php on line 16".  It can't find the FX.php function SetDBData, on line 16,
Below is my whole script.  I can't find any errors.  Could it be the problem is with the FMServer Advanced?  I have the script file in the /Library/WebServer/Documents/.  The database is in /Library/WebServer/Databases.  The path to the required FX.php file is correct.  The database is hosted on FM Server Advanced.  I have the extended priviledges fmxml and fmphp for that account set.  I really don't know what I should check next.  Why is the function not getting called?
thankx,

<?php
require_once('FX/FX.php');
$serverIP = '192.168.1.40';
$webCompanionPort = '80';         
$dataSourceType = 'FMPro9';
$webUN = 'Admin';
$webPW = 'jrough';
$database = 'map_4_.fp7';
$layout = "address";
$dataURLType = "HTTP";

$request = new FX($serverIP, $webCompanionPort, $dataSourceType, $dataURLType);
$request = SetDBData($database,$layout);
$request ->SetDBUserPassword($webUN, $webPW);
$request-> AddDBParam('id',$id);
$result = $fmQuery->FMFind();
$records = $result['data'];


if (strlen($records['linkNext'])< 1) {
  echo "<span class=\"medgraytext\">Next</span>\n";
} else {
  echo '<a href="'.$records['linkNext']."\" class=\"bbody\">Next[/url]\n";   
}

?>

It is supposed to be $request->SetDBData() instead of $request = SetDBData(); Since you are calling the function SetDBData on the request object, and not assigning the result of the function to the request object.
