Hey i bought the billing module a while back and im only getting round to setting it up. it all seems pretty neat. tested the invoice and paypal payment part of the system all looks to be good although i haven't committed to a cash transaction just yet. its on my todo once i'm happy everything is setup ok. a problem i have come across is when clients try to buy an item. any item whether is standalone or addon . when the client clicks order nothing happens immediately. i dont see a change on the screen what so ever but i do receive an email telling me that i have order such an item. i dont get any new invoices either in client or admin panel.. anyone any ideas what the problem could be. everything looks like its set correctly. Thanks in advance BabyDunk
