Here's my solution. I didn't need the transaction counts to solve the problem so I added a validation to make sure the stated transaction count matched the number of transactions just to use that data for something.

@KOBoyle That was my thought at first, but if you do a running total, you are adding the transaction to both the before and after sums so you'll get the same result. If SumBefore = SumAfter, then SumBefore + x = SumAfter + x.
