Have a problem with setting up a payment gateway for my shopping card. I have manage to get almost all right except where the sum is going to be calculated and sent to the payment processor. From the payment processor I got the following coding example: <?php $AgentID="???"; $Key="??????????"; $Description = "Description of item or service"; $SellerEmail = "seller@email.com"; $BuyerEmail = "buyer@email.com"; $Cost = "4"; //Cost of item or service $ExtraCost = "0"; //Shipping $OkUrl = "http://www.yoursite.com/verify.php"; $CancelUrl = "http://www.yoursite.com/error.php"; $RefNr = "123"; //Merchant reference number $GuaranteeOffered = "1"; $MD5string = $SellerEmail . ":" . $Cost . ":" . $ExtraCost . ":" . $OkUrl . ":" . $GuaranteeOffered . $Key; $MD5Hash = md5($MD5string); ?> <form action="https://www.payson.se/merchant/default.aspx" method="post"> <input type="hidden" name="BuyerEmail" value="<?php echo $BuyerEmail ?>"> <input type="hidden" name="AgentID" value="<?php echo $AgentID ?>"> <input type="hidden" name="Description" value="<?php echo $Description ?>"> <input type="hidden" name="SellerEmail" value="<?php echo $SellerEmail ?>"> <input type="hidden" name="Cost" value="<?php echo $Cost ?>"> <input type="hidden" name="ExtraCost" value="<?php echo $ExtraCost ?>"> <input type="hidden" name="OkUrl" value="<?php echo $OkUrl ?>"> <input type="hidden" name="CancelUrl" value="<?php echo $CancelUrl ?>"> <input type="hidden" name="RefNr" value="<?php echo $RefNr ?>"> <input type="hidden" name="MD5" value="<?php echo $MD5Hash ?>"> <input type="hidden" name="GuaranteeOffered" value="<?php echo $GuaranteeOffered ?>"> <input type="submit" value="Send request"> </form> Here is my code: <form method="post" action="https://www.payson.se/testagent/default.aspx" name="gateway_payson" id="gateway_payson"> <input type="hidden" name="SellerEmail" value="<?php echo get_option('gateway_payson_email'); ?>"/> <input type="hidden" name="AgentId" value="<?php echo get_option('gateway_payson_agentid'); ?>"/> <input type="hidden" name="GuaranteeOffered" value="<?php echo get_option('gateway_payson_guaranteeoffered'); ?>"/> <input type="hidden" name="OkUrl" value="<?php echo get_option('gateway_payson_callback'); ?>"/> <input type="hidden" name="RefNr" value="<?php echo $data['orderid']; ?>"/> <input type="hidden" name="Description" value="<?php echo strip_tags($data['description']); ?>"/> <input type="hidden" name="Cost" value="<?php echo $data['price']['total']; ?>"/> <input type="hidden" name="ExtraCost" value="0"> <input type="hidden" name="MD5" value="<?php echo get_option('gateway_payson_receiver');('SellerEmail'); ('OkUrl'); ('GuaranteeOffered'); ('ExtraCost'); ('Cost'); ?>"/> <input type="hidden" name="opt_name" value="<?php echo get_user_meta($userdata->ID, 'first_name', true).'

":" . $Cost . ":" . $ExtraCost . ":" . $OkUrl . ":" . $GuaranteeOffered . $Key; $MD5Hash = md5($MD5string); Any suggestions?
