ai spawn issue

[curtcooll 1]

im using ai respawn script now it sort of does what i want which is forgot its last coord let me explain a little bit more i have a support heli that takes u anywhere now ive got the ai unit to respawn but the trigger i have does not work as the script im using seems to completely disregard it now if i can get the trigger to work alongside the respawn im complete.what im trying to do is make it so heli gets destroyed it respawns done that but getting the ai to spawn while using the trigger which makes the ai the driver and auto mount the heli so it then allows u to recall the helicopter for extract.
