From there, you can set a rate for the level 1 orders (orders with the value of $0 or higher).
Next, add more level(s) of commission rate by clicking Add new level. From there, you can set the minimum order value and commission rate for each level.

Don't forget to click Save changes (or Add if you're creating a new program) to finish setting up the program.
