Your conditional is incomplete. The challenge is asking you to make the arrayCounter function return 0 if the typeof the parameter passed in is a string, number, or undefined. Currently, you're only checking if the typeof the parameter is undefined. You need to include checks in that conditional (just use the OR operator [which is: || ] for simplicity) for the typeof your parameter being a string and a number, as well, and then you'll pass!
