Stage 5 Arrays Functions Arguments Challenge 1

Can someone please help with this crazy challenge? This is the Function Arguments (Return Values) Challenge 1 of 1 Here is what I typed: 

  function arrayCounter (myArray) {
    if (typeof myArray === 'undefined' || typeof myArray === 'string' || typeof myArray === 'number') {
        return 0;
  }
    return arrayCounter.length;
  }

"The Challenge question is this: Around line 17, 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."

I just need to know how this script should work. I tried everything!! :-((

The Challenge reply when I run this is:

"Bummer! If I pass in an array in to 'arrayCounter' of '1,2,3' I get 1 and not the number 3."

You have everything right, apart from the second return, it should be myArray.length, not arrayCounter.length.
