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

[Leo R. Lundgren]

That's exactly what I am trying to point out.

You store using this key in the array:

	$_SESSION['description['.$recid.']']

The key in the array will be "description[123]" for a recid of 123.

You then try to fetch it using this:

	$_SESSION['description'.$recid]

Which is the equivalent of a key "description123" for a recid of 123.

So you are asking for the value in the array at place (key) foo, when having stored it at place (as key) bar. Or the reverse :)
