[FX.php List] Trying to read back an array

[Bob Patin]

Right, I know those 2 are different, but that part seems to work; it populates my database just fine.

And when I put this at the bottom of the first loop, I do see values in my arrays:

		echo $_SESSION['recid['.$recid.']']."   ".$_SESSION['description['.$recid.']'];

It's this loop that doesn't seem to be correct:

  <?php
	  // loop through the recid array and create requests for each item
		foreach($_SESSION['recid'] as $recid) {
			$status = "Open; pending manufacturer approval";
			$description = $_SESSION['description'.$recid];
			$problem = $_SESSION['problem'.$recid];
			$serial = $_SESSION['serial'.$recid];
			echo $recid;
	?>
<<<<<TABLE>>>>>
<?php
}
?>

Should my FOREACH() be different?

Thanks,

Bob
