Thanks, once again, Janwillem.

Going along and employing $lc, if I want to check and see if
anything exists inside the $lc array, what's the best way to do
this? Is there something that returns a TRUE or FALSE and
tells me $_GET holds stuff?

if (count($lc) != 0) {
// nothing set so show the full list
$ShowAllMenus = TRUE;
} else {
// something is set so start grabbing!
$LookAtGet = TRUE;
}

- OR -

if (isset($lc)) {
// something is set so start grabbing!
$LookAtGet = TRUE;
} else {
// nothing set so show the full list
$ShowAllMenus = TRUE;
}

- OR -

if ($lc == NULL) {
// nothing set so show the full list
$ShowAllMenus = TRUE;
} else {
// something is set so start grabbing!
$LookAtGet = TRUE;
}

Thanks, much.
