Hi there! You're doing great, but just like we did in the previous parts of this challenge we are accessing the array by the index. You are trying to unset the array element at the index of "Green", which doesn't exist. The value is "Green", but not the index.

Given that "Green" is now the third element in the array, that will put it at an index of 2.' Take a look:

 unset($colors[2]);

Hope this helps! :sparkles:
