5.2 step 15& 16 HELP!

Someone please assist. I am not sure what I am doing wrong. I know that that the fill in the blank question on the next page is return x / y, (the actual variables), however I cannot get the percentage on the actual module. I don’t know what I am doing wrong, and have altered it any way I can think of. Am I supposed to edit the defined differently? Or how do I name percentage? I am just lost how to get the second part of this to work.

Was able to figure it out. For anyone who is struggling with this step, I recommend going on to 5.3. Step 5 there helped me understand this a bit more for some reason and was able to go back and complete correctly.
