Hi, I am trying to undertake an exercise in which a payroll file is generated. Unfortunately, I seem to be having problems with respect to passing values to functions that calculate pay for various types of employees and tax rates. The code compiles and runs, but generates zeroes for the various calculations that take place in the functions. Any advice or help would be deeply appreciated.

I have included a file, as that might make my code easier to read that the pasted code below. Thanks again, kindly.
