Hi, that’s because your section tags are in the wrong places!
Reread the directions. After your first section ends, you need to open a new one and make sure you include a new closing section tag as well.

When instead you should have gone to the end of the last section and started everything new from there. I’ve reworked your code and given you a hint below.
