TypeError: Error

Question

I have no idea what is wrong, I have checked for typos and everything else I can think of.
The game needs to be handed in tomorrow so help is appreciated!
These are the two errors I receive
at Shooter_fla::MainTimeline/moveEnemy()[Shooter_fla.MainTimeline::frame1:263]

Answer 1

your errors are on lines 83 and 263.
what are those lines and what are the error messages?
