Reindeer Spotter (Javascript)

Level Help
1

I’m stuck on this level and I have absolutely no idea how to solve it. This is my code:

// This array contains each of the pen's positions.
var penPositions = [
    {
        "x": 20,
        "y": 24
    },
    {
        "x": 28,
        "y": 24
    },
    {
        "x": 36,
        "y": 24
    },
    {
        "x": 44,
        "y": 24
    },
    {
        "x": 52,
        "y": 24
    }
];
// This array is used to track which reindeer is in it.
var penOccupants = [
    "empty",
    "empty",
    "empty",
    "empty",
    "empty"
];
// And this array contains our reindeer.
var friends = hero.findFriends();
// Figure out which reindeer are already in their pens.
for (var deerIndex = 0; deerIndex < friends.length; deerIndex++) {
    var reindeer = friends[deerIndex];
    // Check each pen if it matches a reindeer's pos.
    for (var penIndex = 0; penIndex < penPositions.length; penIndex++) {
        var penPos = penPositions[penIndex];
        if (penPos.x == reindeer.pos.x && penPos.y == reindeer.pos.y) {
            // Put the id in penOccupants at penIndex.
            penOccupants[penIndex] = reindeer.id;
            // break out of the inner loop here.
            break;
        }
    }
}
// Tell Merek what's in each pen.
for (var occIndex = 0; occIndex < penOccupants.length; occIndex++) {
    // Tell Merek the pen index and the occupant.
    // Say something like "Pen 3 is Dasher"
    hero.say("Pen " + occIndex + " is " + penOccupants[occIndex] + ".");
}

The problem is even if my hero says “Pen 1 is Comet” or “Pen 2 is empty” (exactly like the clue above my hero.say), Merek wouldn’t do anything. Can anyone help me please?
