Warnings do not prevent compilation.
Also, when there's a warning or error message, you need to post the exact wording and the corresponding line number.

Alright I have edited my former post with my new code, and I am still not getting the results I need.

So, basically you want your code to show the total amount in the slot and the coin return. Am I correct? If that is indeed the case, then I've rewritten your codes with slight modifications. Have a look at it.
