That's not quite it. A string containing a comma is still just one string to the system (and not an array). Also, while altering the initialization might work, I think it's more literally in line with the challenge instructions to add something to the array (on another line) instead.

Hint: a convenient way to add something to an existing array is by using the "push" method.
