Wrong video.
I was just on the lesson 2.8 but when I played the video it was the one for 4.15. I'm not quite up to that yet, I am struggling with 2.8. It has never happened before, and I have just gone back again and it is working fine.
Off to watch again, and again, and again, until it sinks in.

I made a table out of that lesson and it helps a lot. Try it ![]()
