I changed your variable names slightly and your format. It was too messy. Your only fault was the following code:
Pounds++; //This was your code.
TotalPounds += Pounds; //This is the correct code.
Basically, the only problem was you didn't use your "TotalPounds" variable.
Instead, you only incremented your "Pound" variable by one each time.
If you fix these problems your array should work properly.
