I'm really new to VB. This is only the 3 app I've created, and I'm stuck.

I need to code an app that displays total commission earned on sales at different levels. The commission percentage goes up as sales go up.

Should I write a If/else/else/else/else/then statement or something else?

There are 5 different commission levels in the problem. I have my interface designed, but obviously that's the easy part.

Any help would be appreciated.
