I've marked the failing line. This line tries to call a global sum()
function with two arguments. This is a valid error; no such function
exists in the system, and you haven't defined one in the global scope.

I'm not entirely sure what you're trying to do here, so I hesitate to
give you more advice and possibly lead you astray.
