New Post: WorldPay - Junior Select

Can anyone give me advise on configuring the WorldPay Gateway with Select Junior.

I have setup the HTML Redirect as per documentation and at Payment it goes to the WorldPay site, I think the Merchant code is accepted but it complains of Currency or Amount is not recognised.

Is it something I should be adding the ExtraURLs ??

<root>

<HtmlRedirectURL>https://secure.wp3.rbsworldpay.com/wcc/purchase</HtmlRedirectURL>
            <testURL>https://select-test.wp3.rbsworldpay.com/wcc/purchase</testURL>
            <instId>9876543</instId>
    <OrderDescription>Supplement Samples - Order Samples</OrderDescription>
    <Currency>GBP</Currency>
    <ShopperCountryCode>GB</ShopperCountryCode>
    <ButtonImageURL>/Desktopmodules/NB_Store_GatewayWorldPay/WorldPay.jpg</ButtonImageURL>
    <testMode>100</testMode>
    <extraurl>

    </extraurl>

In Worldpay I have set the following.

Integration type Select Junior(60)
Use 3D Secure Authentication? True
Use MasterCard SPA? True
Payment Response URL http://www.supplement-samples.co.uk/Checkout/tabid/4402/stg/4/ordid/ ITEM=cartId>/Default.aspx
Payment Response enabled? True


Any help much appreciated.
