Hi,

Your problem is with this line:

count = 0;

I don’t want to just give you the answer as that’s not going to help you understand it.

Have a think about what this line is doing and then compare it to what you are doing to the count variable for other cases. Then have a re-read of the instructions to see what you should change this line to.

Hope this helps to point you in the right direction :slight_smile:
