Having problem with the Record Collection challenge

This is my code:

    // 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"
    }
};
// Keep a copy of the collection for tests
var collectionCopy = JSON.parse(JSON.stringify(collection));

// Only change code below this line
function updateRecords(id, prop, value) {
  if (prop != "tracks" && value.length !== 0){
    collection[id][prop][value] = value;
  }
  if (prop === "tracks" && collection[id].hasOwnProperty("tracks") === false) {
    var tracks = []; 
    collection[id][tracks] = tracks;
  }
  if (prop === "tracks" && value.length !== 0) {
    collection[id].tracks.push(value);
  }
  if (value.length === 0){
    delete collection[id].prop;
  }
  return collection;
}

// Alter values below to test your code
updateRecords(5439, "artist", "ABBA");

I’m having issues determining the problem in my code. I can’t figure out why this doesn’t work. I’ve tried a couple of alternate codes, but I still can’t seem to solve this problem. Can anyone provide some insight? Thanks in advance.

I cleaned up your code.
You need to use triple backticks to post code to the forum.
See this post for details.

I’ll just point you to the problem areas:

function updateRecords(id, prop, value) {
  if (prop != "tracks" && value.length !== 0){
    collection[id][prop][value] = value; // value is not a property
  }
  if (prop === "tracks" && collection[id].hasOwnProperty("tracks") === false) {
    var tracks = []; 
    collection[id][tracks] = tracks; // what is property tracks here?
  }
  if (prop === "tracks" && value.length !== 0) {
    collection[id].tracks.push(value);
  }
  if (value.length === 0){
    delete collection[id].prop; // prop is variable
  }
  return collection;
}

Thank you very much, I’ve solved the problem.
