i think that was one of the problems, some places the session var was set
back as a string ("0") and other as int (0).
anyway thanks to all, panic over all working now :)

My suggestion would be to checck for isset($_SESSION["temp"]) and if
($_SESSION["temp"] > "0") with quotes .. PHP is very forgiving with data
types, and I've found its much easier to keep track of what exactly is
going on if I reference everything in a string format.

How about something like this:
if ($_SESSION["temp"] > 0) ?
Or if you want to be really sure:
if ($_SESSION["temp"] > 0 && $_SESSION["temp"] != "")
ORif you want to be sure the value is a number as well:
if ($_SESSION["temp"] > 0 && $_SESSION["temp"] != "" &&
is_numeric($_SESSION["temp"]
if( !empty($_SESSION["temp"])&& is_numeric($_SESSION["temp"]) &&
$_SESSION["temp"] >= 0 ) {
...
}
Something like this may work, first check to see if its not empty, then
numeric, then if its greater than or equal to 0. If all three
conditions are true then it'll execute the "..." block.
Plea
$var = 0;
if(!is_int($var)) {
echo '$var isn\'t numeric';
}
and simple 'not' is going to ignore '0'. To check wherther a value is an
integer use is_int() or is_numeric(), which are the same things anyway.
If you care that the value is also higher than '0' add [ and $var>0] as
the secon
