| pass struct into function |

I am trying to pass a struct into a function and it isn't working. There are no errors when I compile, but the led that should blink doesn't, so the counter isn't getting reset. I believe that I have tested everything else and there aren't other problems. Does anyone see the problem?
Thanks!

Hi
I don't understand why passing the struct to a function, when the struct is declared as global?
Maybe just my poor understanding. |
