Solved: Varying Commission (excel)

Hi, really hoping someone can assist here.

I have been tasked with creating an excel doc that calculates a salesmans commission, the only catch it that is has multiple levels to it.
I have a sales value, and on sales up to £10 they get 0% commission, between £10 (£10.01) and £20 they get 5%, between £20 (£20.01) and £30 they get 10% and anything after that is at 10%.

Any assistance would be appreciated

thanks
