using tokens

I'm using Auto Nodetitle along with CCK Fullname, both of which support Token.

I use the token [field_fullname], which is the name I gave the field I had created of type CCK Fullname, but I'm unable to get Auto Nodetitle to set the node's title field based on the value of CCK Fullname.

In "Automatic title generation" I chose "Automatically generate the title and hide the title field" and entered the token [field_fullname] then saved the content type and created an instance node, but its title was set to the literal "[field_fullname]".

Next I tried to check "Evaluate PHP in pattern" and in "Pattern for the title" I typed:

<?php
  $token = '[field_fullname]';
  return $token;
?>

like the example in README.txt under Advanced Use: Combining tokens and PHP but I still got the same result

Just in case there were something wrong with CCK Fullname, I tried both ways with the "Text" field supplied with CCK; changing the token to use the correct fieldname, of course, but got the same result again.

Am I missing something?

Thank you and regards,
