You are never modifying the running total.  I think you want to
initialize the running total to the first guess outside the loop, then
add guess to it when you read a new number.  You can add to a variable
like this:
              running_total += guess

this is approx. the same thing as

              running_total = running_total + guess

I don't think subtotal and running_total need to be separate variables.
