Cannot sort calculations in tables....

Guys; See the attached file, which includes three tabs, each of which has a table with a number next to an entry that is colored.

What I'm trying to do on the third tab, titled "calculations," is just subtract the number from the middle tab (data 2) from the number in the first tab in that same row (data 1), do this for every number in the table, and have the results show in the table. This part is already done.

Here is the problem: I can't get the "calculations" table to sort...I need to sort those results by the numbers from least to greatest. It seems to be sorting randomly.

Not sure what the issue could be. Would appreciate any help. Thanks alot.
