You already have your help-  the traceback tells you everything you
need to know. If you don't understand what the traceback is saying,
come back here and specifically ask about the part you have trouble
with. But we do expect that you will at least attempt to solve this on
your own before coming here.

Now, what does the traceback say you are doing wrong? What are you
handing the function and what should you be handing the function?
