I am trying to increase/decrease the value of $_SESSION['count'] by 1
after clicking on a link e.g index.php?gotoWk=nxtWk and index.php?
gotoWk=lstWk. I'm sure you will get the drift if you look at the code
below.

However, this code seems to be unreliable. Is there a more robust way
of achieving the same thing?

Many thanks,

Chris

if (!isset($_SESSION['count'])) {
$_SESSION['count'] = 0;
} elseif($_REQUEST['gotoWk'] == "nxtWk") {
$_SESSION['count']++;
} elseif($_REQUEST['gotoWk'] == "lstWk") {
$_SESSION['count']--;
}
