arrayCounter passes 'number'

Task: Create a function named 'arrayCounter' that takes in a parameter which is an array. The function must return the length of an array passed in or 0 if a 'string', 'number' or 'undefined' value is passed in."

When I check my code, it says "Bummer! If I pass in an array in to 'arrayCounter' of '1,2,3' I get 0 and not the number 3."

Question : When the task asking to return 0 if 'number' passed in. Isn't 1,2,3 ('number') should return 0 when it passed?
