[Kenneth Nyström]

So I have tried and tried and tried; to change an objects mass thru a script.

I basicly want to have an trigger (activate) "change" a mass in a diffrent object thru two scripts

I have done and redone this so many times my head is spinning so hard ; I cant figure this out now. 
(I kid u not spent 20 hours to try solve this on my own)

.............
trigger script be like: set the "global" value with
 
getmass=2

.....
object script

if getmass=2 then SetMass (5)
........
