how can I pass this on

[fazzfarrell]

I have created this

[code]
<?php
//Rob Farrell and Leyon Nevett: ad up cost x currency
            $number1 = $HTTP_SESSION_VARS["icJag"]->col("Total");
$number2 = $row_rsCurrency['Rate'];
            $newnumber = ($number1 * $number2);
echo $english_format_number = number_format($newnumber, 2, '.', '');
$totalCart = $english_format_number = number_format($newnumber, 2, '.', '');
?>[/code]

I want to pass on $totalCart on to
[code]
<?php

if (isset($HTTP_POST_VARS["imxPPForm1"])) {
$IMX_PP = new PayPalSIP();
$IMX_PP->business = "[email protected]";
$IMX_PP->image_url = "logo.gif";
$IMX_PP->item_number = $HTTP_SESSION_VARS["icJag"]->col("OrderID");
$IMX_PP->item_name = "Jaguar";
$IMX_PP->currency_code = $row_rsCurrency['CurrRate'];
$IMX_PP->quantity = "1";
                $IMX_PP->winName = "paypal";
$IMX_PP->toolbar="no";
$IMX_PP->location="no";
$IMX_PP->status="no";
$IMX_PP->menubar="yes";
$IMX_PP->scrollbars="yes";
$IMX_PP->resizable="no";
$IMX_PP->width="700";
$IMX_PP->height="500";
$IMX_PP->amount = $totalCart;
$IMX_PP->return = "success.php";
$IMX_PP->cancel_return = "cancel.php";
$IMX_PP->create();
$url = $IMX_PP->_url;
header("Location: $url");
