Hi,
I have no idea what is wrong with my code. Can someone please help me to detect where the problem is?
Thanks,

Your code so far


// Setup
var collection = {
2548: {
  album: "Slippery When Wet",
  artist: "Bon Jovi",
  tracks: [
    "Let It Rock",
    "You Give Love a Bad Name"
  ]
},
2468: {
  album: "1999",
  artist: "Prince",
  tracks: [
    "1999",
    "Little Red Corvette"
  ]
},
1245: {
  artist: "Robert Palmer",
  tracks: [ ]
},
5439: {
  album: "ABBA Gold"
}
};

// Only change code below this line
function updateRecords(id, prop, value) {
if(prop !== "tracks" && value !== ""){
collection[id][prop] = value;
}
else if(prop == "tracks"){
  if (collection[id].hasOwnProperty("tracks")){
    collection[id][prop].push(value);
  }
  else{
    collection[id][prop] = [];
    collection[id][prop].push(value);
  }
}
else if(value == ""){
  delete collection[id][prop];
}


}

updateRecords(5439, "artist", "ABBA");
