Google Checkout XML invalid value

[Infernus]

I'm using a plugin called http://www.jigoshop.com with Wordpress (both the latest versions) and I'm having problems with their Google Checkout gateway.I've tried their support but yet to get a response.I'm getting the following errors when trying to order something:\[quote\] Error parsing XML; message from parser is: Invalid value for attribute unit-price in shopping-cart.items.item-2.unit-price: Required field must not be blank\[/quote\]In the Google merchant console this translates to:"XML that we recieved"\[code\]_type=checkout-shopping-cart&shopping-cart.merchant-private-data=http://stackoverflow.com/questions/10521864/273&checkout-flow-support.merchant-checkout-flow-support.continue-shopping-url=http%3A%2F%2Fwww.carolinemontagu.com%2Fv2%2Fevents%2Fcheckout%2Fthanks%2F&checkout-flow-support.merchant-checkout-flow-support.edit-cart-url=http%3A%2F%2Fwww.carolinemontagu.com%2Fv2%2Fevents%2Forder%2F&shopping-cart.items.item-1.item-name=Leadership+Success%3A+Early+bird+%26%238211%3B+19th+Oct&shopping-cart.items.item-1.item-description=&shopping-cart.items.item-1.unit-price=205.83&shopping-cart.items.item-1.unit-price.currency=GBP&shopping-cart.items.item-1.quantity=1&shopping-cart.items.item-1.merchant-item-id=211&shopping-cart.items.item-2.item-name=Shipping&shopping-cart.items.item-2.item-description=&shopping-cart.items.item-2.unit-price=&shopping-cart.items.item-2.unit-price.currency=GBP&shopping-cart.items.item-2.quantity=1&shopping-cart.items.item-2.merchant-item-id=\[/code\]"XML that we sent"\[code\]_type=error&error-message=Error+parsing+XML%3B+message+from+parser+is%3A+Invalid+value+for+attribute+unit-price+in+shopping-cart.items.item-2.unit-price%3A+Required+field+must+not+be+blank&serial-number=3f096700-bb6f-4e28-8740-f6ffa0d09aeb\[/code\]I've had a look through their code and can find this that corresponds to \[code\]shopping-cart.items.item-2.unit-price\[/code\]:\[code\]private function formatOrder(jigoshop_order $order) { $result = array( '_type' => 'checkout-shopping-cart', 'shopping-cart.merchant-private-data' => $order->id, 'checkout-flow-support.merchant-checkout-flow-support.continue-shopping-url' => get_permalink(get_option('jigoshop_thanks_page_id')), 'checkout-flow-support.merchant-checkout-flow-support.edit-cart-url' => get_permalink(get_option('jigoshop_cart_page_id')), //shipping-taxed ); $i = 1; foreach($order->items as $item) { $prefix = "shopping-cart.items.item-$i.";//shopping-cart.items.item-1.item-name $result[$prefix.'item-name'] = $item['name']; $result[$prefix.'item-description'] = ''; $result[$prefix.'unit-price'] = $item['cost']; $result[$prefix.'unit-price.currency'] = get_option('jigoshop_currency'); $result[$prefix.'quantity'] = $item['qty']; $result[$prefix.'merchant-item-id'] = $item['id']; $i++; } $prefix = "shopping-cart.items.item-$i."; $result[$prefix.'item-name'] = __('Shipping', 'jigoshop'); $result[$prefix.'item-description'] = ''; $result[$prefix.'unit-price'] = $order->order_shipping; $result[$prefix.'unit-price.currency'] = get_option('jigoshop_currency'); $result[$prefix.'quantity'] = 1; $result[$prefix.'merchant-item-id'] = $order->shipping_method; return $result;}\[/code\]Can anyone help with this problem?
