help with @follow

[v3001]

well i was jsut stupid. got everything working up to now.
but if anybody happens to know, why i cant get any mobs to follow me anymore, id be greatfull for some help.
i remember that it is possible to get units to follow your character and fight for you. but i dont get it working anymore.
i use:
@setplayer(getobjectbyid("12345"),0)
@follow(getobjectbyid("12345"),getunitofplayer(0,0))
@run(getobjectbyid("12345"))
but everytime my company or myself kills an enemy, the unit just runs away again, giving me the message: "new motivation sentry with power 50"

any ideas how to get them to follow me always?
