I am working on a modification for my Admin Orders page. This is really a separate PHP file that runs just before the footer. However, I have

Code:
<?php require(DIR_WS_INCLUDES . 'myfile.php'); ?>
But it does not work.....if I change 'myfile.php' to 'footer.php' the next line executed in is 'footer.php'. When the first version goes through i get send to a another zencart function

Code:
_sess_write()
So do I need to register my files somewhere? These two files are located in the same directory.

Thanks
Chris
