This worked.
//eCart Rule
function WAEC_eCart1_Country() {
$totalShipping = 0;
if (true && ((sizeof($this->Items) > 0) && ((isset($_SESSION['shipcountry'])?$_SESSION['shipcountry']:"") > "0"))) {
$totalShipping += $_SESSION['shipcountry'];//Result
}
return WA_eCart_FormatNumber($totalShipping, $this->ForceDecimalsC, $this->DecimalPlacesC);
}
//eCart Rule
Thank you for your assistance. Hope this helps someone else.
