Average Calculation

ProgrammerXYZ (23)
I have to write a program in which I sum and average all the data for the population of Florida, and Mississippi. I think I did everything right, except, I seem to be getting the wrong averages.

The output is supposed to be MS: 79075.5 FL: 65785.2

I am getting MS: 84123 FL: 62151.4

This is the code I have so far:

Why is the SumPopulation function empty? What is it supposed to be doing?
