Oscommerce PWA problem

My website is currently using Paypal Without Account Module. The exact version is: PayPal Pro for osCommerce 2.2MS2+ Direct Payment & Express Checkout Developed and maintained by: Brian Burton (dynamoeffects) I have some minor issues with this module. Firstly I'd like to ask whether UK customers can make payment through paypal from this module. As i have received some feedback that they can not make payment via paypal (mostly customers outside the US). Secondly, the paypal transaction record doesn't show the correct number of items that the customer ordered, and it always stayed at 1 for whatever amount of items per order. For example, if the price of an item is $2, and the customer orders for 6, then the paypal payment transaction details page displays the correct total price, which is $12, but the wrong quantity (1 here). Qty Item Price 1 925 silver Core... $12.00 USD Amount $12.00 USD I would really appreciate if someone could fix these problems for me. PS: When fixing the site, I would like to have a simple blank page setup just to tell the site is under maintenance, so that the customers can be informed.
