Eric,
that function does not exist on my pp_confirm.php page, the closest equivalent on the page is:
<?php
$WA_PP_ECO_GetResult = WA_PP_ECO_SOAPObject();
if ((isset($_GET["token"]) && isset($_GET["PayerID"])) || (isset($_SESSION["PayPal_ECO_Token"]) && $_SESSION["PayPal_ECO_Token"] != "")) {
$WA_PP_ECO_GetResult = WA_PP_ECO_Get_Post($i8_username, $i8_password, $i8_signature, false);
}
?>
