4.3 Step 10 and 11

I have been working on this for a while now and cannot figure out where I am going wrong. I think what is holding me up is numbers that are divisible by 3 and 7. Any help or push in the right direction is appreciated!

It would be helpful for you to add your code. Hard to tell you whats broke if we cant see it?

I finally realized I was using / when I should have been using %.
