Got the switch working...of sorts.
Put this into init_sessions.php
//set $_SESSION['catflag'] if not previously set
if (!isset($_SESSION['catflag'])) {
$_SESSION['catflag'] = 0;
}
//end
Used this for header_php.php

?>
the flag is set when it should be and will enable a new script to be run for displaying sub sub category images....
except one issue:
If you navigate back to the home page, or directly to another category then catflag is still set at 1.
Any way of resetting the flag when index or a new category is loaded?
When i get this working i'll post it for others as it should prove useful.
Thanks for any help.
