Thanks Igor. That did it. I knew it couldn't be that complicated.

the "A=B" is what you are missing.

RE: Replacing a panel with another panel
So how would I reference B rather than A on all subsequent calls after the first. Is it as simple as checking to see if A does not have some property set? Then just use an if/then/else statement to use the correct panel.

My guess is that you are referencing the the first panel again. When you replace panel A with panel B, panel A loses it's reference to the parent (which goes to B obviously), so if you were to replace on A again, you get an exception like that. The solution is to reference B rather than A.
