Hey! I am following along to a tutorial step by step and I have got to 7min 42sec into the tutorial and I put in the code like it said, but my headers did not change like the one in the tutorial and I don't understand what i am doing wrong? Do i need to add anymore code somewhere?

Here is the tutorial I am following along toohttps://www.youtube.com/watch?v=GNamx737AAU
