passing var of go to detail page more than once

Thank you for your input.

Would you mind...helping me out with this.

So where would I start this session (what page do I put it on to start..?)

Do I need to reference it on the results, details, and menu.php pages?
menu.php is the only page that isn't getting the detailsID

I don't have much of a clue on the syntex structure of a session. WADA has constructed the sessions I have...(embarrassed to admit...) But when I try to look at the sessions in the applications...there isn't any detail there either...

I know I have to have this:

<?php
if (!isset($_SESSION)) {
session_start();
}
?>


I have attached my menu.php page which has the query with the detailsID=colname...

Any help would be greatly appreciate
