                        }
                        }
        }
?>

Now, when a user is logged in, nothing is displayed. It doesn't seem to get the Y or N from the group file and match to the member group.

Sample line from memberfile looks like:

1|User|Password|0|1|1

Sample line from groupfile looks like:

1|Admin|Y|Y

Any help?
