I have refunded the incorrect payment through PP, and gone back to the items sold page -> Actions -> send revised invoice
But it is not working, whenever I hit the recalculate button a minus sign pops up with the original amount down in the total amount box!! Now what - should I wait and it will eventually allow me to do invoice. by attempting this immediately after refund is it too soon?
Shy pansy your answer was so helpful, got any ideas with this?
