ok thanks, it works great.
ok I thought I might just edit this post with the next question rather than starting a new topic.
ok I did'nt know only one ship can be dockked at one time,
as soon as I removed the ship already docked with the station the ship I wanted to move in and dock, did so.
anyway now I'm trying to get it's engines to go off (disabled) when it docks with the station.
(edit) ok I still have'nt been able to turn the ship's engines off (disabled it) after it docks, whats the proper way to shut down it's engines after this ship docks with the station?
thanks for all your help karajorma you've certainly been a great help here,
