For some reason the letter grade ("NewTestTwo") wont display, am I not returning it correctly to the main function?

grade converter (the one that takes 2 parameters) returns a value but you're not doing anything with it.

I think you meant NewTestTwo = grade_converter(testTwo,NewTestTwo);

the other grade converter function (1 parameter) is used in the same way, but since you do the output inside of that function you still see the result
