# CASH REGISTER - correct output can't pass two tests

Tell us what’s happening:
I’ve run through all the different tests and get output IDENTICAL to the expected and yet I still fail the second and third tests. I’ve been working on this one for three days and cannot see any reason why I can’t pass these two tests. I am aware that there are vastly different avenues to take in regard to this challenge, but I’m right there with my method! Any help pinpointing what it is about my method that is hanging up would be greatly appreciated.
