Yes to both.
If I use Wolf's code;
Condition: Con1 && Con2 && Con3
On activation : Blah blah
then it asks me for missing (
Fixed it.
Although I originally said my condidtions were Con1, 2 etc. When I wrote the script I made the conditions 1Clear, 2Clear, etc. ArmA Doesn't like the first character in a condition to be a number so I swapped the number to the end and made the conditions Clear1, Clear2 etc. Now it works fine.
Thanks for the help guys.
