[term] not working when firstly submitting.

Hi...I downloaded the latest realise of autonodetitle. The [term] doesn't seem to work when I first submit a node. It doesn't display the term. But when I edit and then submit, it does. Why exactly is it doing this? Is there something wrong with the code or does it conflict with another module?

I basically use php code to retrieve the child term and parent term such as:

$termpath = '[termpath]';
list($parenterm, $childterm) = split('//', $termpath);
return $parenterm . ' ' . $childterm;

which worked when i was at the start of developing my site. But now it doesn't.

I would appreciate if someone give me an answer

thanks,

Mary
