resetting variables...

[greenber]

Attached is a php file I'm having trouble with. A live version can be found at http:jewishtreasures.com/zz.php

A variable, '$tt' determines if this is the first time through, tt==1, and opens the database and selects a random record if so.

tt==1 displays layer1, upon submission, layer2 is displayed, and $tt=$tt+1.

I want to hide the layers and reset $tt to zero upon a submission of layer2. I also want to set to $tt=0 when the "trivia" link is hit on the page, but I can't seem to do so: <? $tt=0?> is hit no matter where I try to hide it.

What am I doing wrong?

Thanks!

If I'm reading you right, you want to switch
between layers tt = 1 and tt = 2 on successive
views of the page. Also, you want the trivia
button to view the page with layer 1.

If that's the case then try this ...

session_register('tt');

if($_GET['trivia'] == 'yes'){
	$_SESSION['tt'] = 1;
} else if(!isset($_SESSION['tt'])){
	$_SESSION['tt'] = 1;
} else {
	if($_SESSION['tt'] == 1){
		$_SESSION['tt'] = 2;
	} else {
		$_SESSION['tt'] = 1;
	}
}

The 'trivia' link should just point to the
current page with the appendage '?trivia=yes'
