Accessing Objects Properties with Variables HELP

Tell us what’s happening:

Code is is giving me the players name for number 16 but it still wont let me pass??

Your code so far

// Setup
var testObj = {
  12: "Namath",
  16: "Montana",
  19: "Unitas"
};

// Only change code below this line;

var playerNumber = [16];       // Change this Line
var player = testObj[playerNumber];   // Change this Line

Thank you, I cannot believe that it was something so simple holding me back, I suppose im finding out the longer you look at code the harder it becomes to see the flaws. Thank you again.
