Always a good idea. I always snap a few pics when working on something new.

You'll get there. Just keep working on stuff. I learned a lot through trial and error when I was younger.

I couldn't see your white gasket very well. but yes, what I would expect on the bottom of that tail piece is the one in the picture, the beveled gasket. In the it video looks kind of like it's flat but if it fits and it seals, that's all that matters. These things are not under much pressure.

Cuz it looks like a tailpiece gasket. And experience.

Lol, Well the green gasket is the one I would expect to see at the top but the white one looks a little different than what i would expect on the bottom joint but if it's working then I wouldn't worry about it.

Yep. You got it!

Look at the way you are holding the "trap" and the position of the tailpiece under the sink at the end of the video, keep them in that position but try switching the position of the green seal and white seal.

Regular chicken flavor? Meh. But Golden Chicken Flavor? Oh yeah!
