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 :)
