Doesn't the SELLERPAYPALACCOUNTID work in the

Question

i use the SetExpressCheckout for my website. On this side I have some products. Each product has an other recipient. So I fill the parameter "PAYMENTREQUEST_0_SELLERPAYPALACCOUNTID"

    $padata =   '&CURRENCYCODE='.urlencode($CurrencyCode).
            '&PAYMENTACTION=Sale'.
            '&ALLOWNOTE=1'.
            '&PAYMENTREQUEST_0_SELLERPAYPALACCOUNTID='.$email.            
            '&PAYMENTREQUEST_0_CURRENCYCODE='.urlencode($CurrencyCode).
            '&PAYMENTREQUEST_0_AMT='.urlencode($ItemTotalPrice).
            '&PAYMENTREQUEST_0_ITEMAMT='.urlencode($ItemTotalPrice).
            '&L_PAYMENTREQUEST_0_QTY0='. urlencode($ItemQty).
            '&L_PAYMENTREQUEST_0_AMT0='.urlencode($ItemPrice).
            '&L_PAYMENTREQUEST_0_NAME0='.urlencode($ItemName).
            '&L_PAYMENTREQUEST_0_NUMBER0='.urlencode($ItemNumber).
            '&AMT='.urlencode($ItemTotalPrice).
            '&RETURNURL='.urlencode($PayPalReturnURL ).
            '&CANCELURL='.urlencode($PayPalCancelURL);

But when I get the success page, the array of the transaction shows the recipient of die API-Account. Is that a problem of the sandbox or is it my problem? Thanks for your answers and help!
