Return desired result based on a condition (to show 0% instead of #div/0)

Hello,
Well so much for being done, if any one can help with the code below, would appreciate.
I am getting the #div/0 error again but elseware on the below code.

=IF(H9="", "", IF(H9="0", "0%", H18/H9))

Is there somthing I can add in here so when h18/h9 = 0 to show 0% instead of #div/0?
