How to make this work? Survey Form

So I checked all 17/17 then I started using CSS Grid, I made a 3 column layout.
which I want to keep, but when I close my main “wrapper” div I get checked 15/17. Which is crazy considering I leave one div not closed. I’m super confused and need some guidance on this :

Why when I close the div my projects do not meet all of the criteria?
How to keep the same 3 column grid with meeting all the requirements?

The project is here:

Hello! Your <textarea> and <submit> have to be inside the <form>. Right now, you have them in the <footer> which is outside the form. I moved them and got 17/17.
