No worries!
For line 39, you put “enters from to screen right”, you need to put "enters from (right or left) to screen right.
There’s no such thing as zone “-1” for line 52.
You have two backgrounds back to back, there’s no reason for line 14 or line 35 to exist.
I can’t fully see line 18 or 41 so I’m not sure exactly what you did wrong yet.
Hope that helped <3
