[FX.php List] This is driving me crazy

[Bob Patin]

What's wrong with this picture? I get no errorCode:

$query=new FX($serverIP,$webCompanionPort, $dataType, $scheme);
$query->SetDBData($webDB,'web_InternAppl',1);
$query->SetDBPassword($webPW,$webUN);
$query->AddDBParam('webUsername',$username);
$queryResult=$query->FMFind();
echo 'Error code: '.$queryResult['errorCode'];
