This normally happens when you start to place an order, open another window or tab and start another order, then return to the original one to continue.
For security reasons, and to stop you placing duplicate orders, it's only possible to place one order at a time.
You'll need to make sure that you only have one window or tab open on the John Lewis Broadband site and start your order again.
