Specifically what do you mean by 'set" it above the if? I've tried
various methods of "setting" $_SESSION['cntr'] before the IF, but ...
nothing changes or I get a Notice of an undefined variable if I try to
, say, echo $_SESSION["cntr"] . "<br />"; , it also reports 0! So
somehow, the session variable never makes it back to the first page.
Further to the above, I do not have a value pre-set for the related
input field.
Here's the code from the second page where an error is being purposely
generated if it helps any:
<code>
echo "Counter was : " . $_SESSION["cntr"] . "<br />";
if(strlen($zip)< "5") {
$cntr=$_SESSION["cntr"] + "1";
echo "Counter is " .$cntr."<br />" ;
}
</code>
Both echo statements work, with the expected results when an error
occurs. It's 0 for the first echo, and 1 for the last echo.
Apparently somehow I am destroying the contents of the session var but
darned if I can find it!
An further thoughts or comments would be appreciated; feel free to be
brutal; I'm sure it's something very basic I'm doing. I am in the
process of creating files with nothing but the counter session to get a
closer look maybe.
My sincere apologies for not providing entire code for the pages; it's
simply not allowed.

No, but ... if I do, it shows $SESSION["cntr"] to be "0". And that
means it's somehow trashing the vars somewhere I'm not aware of.
Thanks much for your response; it at least put things into a better
prospective for me. I think :)
