Welcome to the forum @janaakl721

When I test your code, the incorrect text message is output.

When there are no quarters in the register, the function show move to the next lower cash demonination.

Happy coding

hello, maybe because you havent changed cid , like you used the old one which had quarters

4

Maybe. Did you test it out?

All of these global variables will cause problems because the tests call the function back to back, and these values will not be reset. You should move everything into the function except price and cid

thank you so much, that helped
