Excel pivot table not responding

I haven't checked all the monetary columns but columns M to R you have formatted as currency (two decimal places). If you change the formatting of those columns you will see that the real values are somewhat different than what currency displays.
You are testing using values that you entered and not calculated values. That will certainly explain some of the differences. To find all of the differences, all the names would have to be converted to ranges to see what is happening. In addition, you are using percentages and that is another area where errors in precision can occur.
