From what I've read so far, you want the ability to go back to the Discount field if the user accidently got to the Amount Recieved field. The problem is that LostFocus() in the Amount Received field fires various other commands.

I see two possibilities.

1. Best, I think, is to move the Drawer Open, Pole Display etc. to a separate command button. This button can be disabled initially and the LostFocus() in the Amount Received field can enable it. Preferably, it should have validation logic so that it won't do anything unless all the necessary information is present.

2. Check the value in Amount Received. If it is some special value (zero, negative, or maybe even character) set focus back to the Discount field. Otherwise, perform the current set of tasks.

I think my first alternative is far better, but screen real estate, current interface, etc. may make second option better. I wouldn't be surprised to find a better solution offered elsewhere, but I think either of these ideas would work.
