It should be fine if $tu would translate to NULL. The script
handles this case. But I'm afraid you have something else there,
like another deeper error that prevents the $tu variable to be
evaluated.<br clear="none">
<br clear="none">
Do you see any other errors before the mentioned ones ? what is
the type of route where you do the test ?<br clear="none">
