Really simple question about notlogged in template

This is probably very bery simple but i guess we all have to start somewhere

I have a file bank.php which displays a bank when logged in but for users that are not logged in or guests they get the standard show_nopremission

I have written a template bank_notloggedin template i want to be displayed if a user is a guest or not logged in.

I think i have to change this bit in bank.php

if ($bbuserinfo[username]=="Unregistered"){
show_nopermission();

}elseif ($process){


but i am not sure to what.

Any ideas?

i have changed the second line to

\\ bank_notloggedin();

but now i get a blank page..
