Simple PHP Filemaker script calling

Hello,

We are trying to make a FMP 11 combination to display a list of records that are only open status.

We made a php site with the php site assistant.

Now we want to add to the lsit the option to only show the open records (open in meaning the status is open)

When we try to add this :

$newPerformScript = $fm->newPerformScriptCommand('FMLijst', 'FMLijst');

$result = $newPerformScript->execute();

when we add this (layout is FMLijst, and scripts is called FMLijst. The list stays long.

There only 4 records with the status open.

We want to have the control thats why we want to do with a script.

What do we do wrong .. ?
