you FIRST have to record a nav route (in doors - be sure to put 2 or 3 points around corners ie one right at start, one half waty thru turn and last just outside the turn in the new direction - really helps).
THEN the next time thru you can 'run' the script to navigate thru.
I usually make/create a script using the toughtest toon i have, and don't bother fighting just concentrating on making the script.
