Counter help

[nblackwood]

Hey all. I have a counter i developed. Everything works well, except when the counter reaches 0 when counting backwards, I need it to stop it doesn't. It just continues into the negative values. Here is my code:

 

<?php
$AddFields = $_SESSION['NumFields'];
$RemoveFields = $_SESSION['NumFields'];



	if(isset($_POST['Add']))
	{
		$AddFields = $_SESSION['NumFields'] ++;
		$TotalFields = $AddFields +1;
	}

	if(isset($_POST['Remove']))
	{
		$RemoveFields = $_SESSION['NumFields'] --;
		$TotalFields = $RemoveFields -1;
	}
?>

 

Help is appreciated.

Try

if(isset($_POST['Remove'])&&$TotalFields>=0)

Im assuming that TotalFields was th variable you were talking aout.
