When doing challenges with multiple parts you need to keep the code from each part around. If you remove or modify your previous code then you will usually not be able to complete the task.

So you need to add the code from Task 1 back again. Also since the code from Task 1 adds an item to the start and end of the array you have to change your indexes to reflect that, like this:

<?php

$colors = array("Red","Green","Blue");

//add modifications below this line
array_unshift($colors,"Yellow");
array_push($colors,"Black");

$colors[1] = "Magenta"; // Index increased since "Yellow" was added at the start of the array
$colors[3] = "Cyan"; // Index increased since "Yellow" was added at the start of the array

That will allow you to complete the second task.
