Had some fun building the Commission Calculator.

In my version I write out the Sales Reps and their Commission Rate to a text file. I also added an ID so I can look up their Commission Rate based on the selection from my Combo Box. For this I used a dictionary (Name Value Pairs). Each of my sections on the Form have full validation to make sure none of the required data is omitted.

Too much code to post here but if anyone really wants to see it I can make several images and post them separately.
