I have run into a problem with this challenge

Tell us what’s happening:
Hi! Still cannot finish this project. I have an old thread about it, but I don’t want to bump it to the top of the forum. It says “cannot read property push of property” and I don’t know why.

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: [
    "Little Red Corvette"
1245: {
  artist: "Robert Palmer",
  tracks: [ ]
5439: {
  album: "ABBA Gold"

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

updateRecords(5439, "tracks", "Take a Chance on Me");

Challenge: Record Collection

Link to the challenge:

collection[id] gives you access to each nested object. collection[id][prop] gives you access to a particular property of said nested object(the one with that id).
collection[id[prop]] isn’t going to work as intended and neither is id.hasOwnProperty().

Hi! I have fixed that issue yet still has same problem.
