It's asking you to print a month depending on what item it's currently iterating over in the loop.

Therefore: 1 = January, 2 = February and 3 = March.

So when you encounter a '1' you want print January:

  if month == 1 {
  } // Then here you would write an else if statement for the result of '2' and so on...

Hope it helped! :)

You also need to take the space out between the printl and the (). It should be println() not println (). Stephen is write. You have to put the string you want to print into the ().
