You're trying to run this from within the Editor by clicking Evaluate
Cell, but when you do this, it has no input arguments defined.
Evaluate Cell only works in a script, not a function.
You need to either: go to the Command Window and call it with
arguments; or write a script that calls the function, then execute
using Evaluate Cell.
