I have an overlay problem

You’re using & instead of @. For something like this, you either need to do
@overlay WCAESAR ARM shifts to 175 69 in zone 1
@overlay WCAESAR ARM shifts to 175 128 in zone 1 in 3
@overlay WCAESAR ARM shifts to 176 128 in zone 1 in 1
etc.

OR

@overlay WCAESAR ARM shifts to 175 69 in zone 1 THEN overlay WCAESAR ARM shifts to 175 128 in zone 1 in 3 THEN overlay WCAESAR ARM shifts to 176 128 in zone 1 in 1
etc.
