Shipping not calculated on pp_confirm.php page

Hello WebAssist staff, I have a problem that has been vexing me all day. When my customers pay using PayPal express checkout the UPS shipping is not displayed on the pp_confirm.php page. The shipping is calculated and displayed on the pp_checkout_success.php which takes my customers by surprise. The UPS shipping is calculated correctly on my regular local checkout confirm.php page. Can someone look into this as I need to be able to show the UPS calculation before my customer clicks the final confirmation button to complete a sale.

Regards,
Robert

Update line 273 from:

if ($_SERVER["REQUEST_METHOD"] == "POST") {

to:

if ("" == "") {

This issue is that it is only calculating shipping after the form posts and not before the page loads like it needs to.

Ray, in addition to your suggestion of using

if ("" == "") {

I have to change lines 294 - 296 from:

$Shipping_Parameters["ShiptoCity"] = "".((isset($_POST["shipping_city"]))?$_POST["shipping_city"]:"") ."";
$Shipping_Parameters["ShiptoState"] = "".((isset($_POST["shipping_state_province"]))?$_POST["shipping_state_province"]:"") ."";
$Shipping_Parameters["ShiptoZip"] = "".((isset($_POST["shipping_postcode"]))?$_POST["shipping_postcode"]:"") ."";

To the following:

$Shipping_Parameters["ShiptoCity"] = "".WA_PP_ECO_GetValue($WA_PP_ECO_GetResult, "CityName") ."";
$Shipping_Parameters["ShiptoState"] = "".WA_PP_ECO_GetValue($WA_PP_ECO_GetResult, "StateOrProvince") ."";
$Shipping_Parameters["ShiptoZip"] = "".WA_PP_ECO_GetValue($WA_PP_ECO_GetResult, "PostalCode") ."";

All in well. Thank you for your help.

Regards,
Robert
