No, I don't think that will work. gPreviousScreen contains an integer, and
sprite(6) will return a sprite reference. sprite(6) - gPreviousScreen isn't
a valid operation.
I'm not sure what you're trying to do, though. You say you want to keep
track of your previous screen, but I'm afraid I can't tell what you're
after. Can you give a bit more detailed description?
