It's part of a basic debugging strategy. If a script is not working,
start breaking it into smaller pieces to see how variables change as
it flows. You are using two pages and session variables. You don't
know if the session variable is being set wrong, or is not accessible
to page 2, or page 2 is faulty. So...

on page 2 insert the line:

$_SESSION['cntr']=1;

before:

if($_SESSION["cntr"] > "0") {

If the results are still screwy then the problem is on page 2. If they
are correct, then the problem is page 1 or in accessing the session
variable on page 2.
