trigger activated by player seeing specific unit?

[seldom]

i know this is possible, and i have dissected the mission [8C]SoftLanding_V3 by Vortrog to have a look at how it is done, but alas i cannot seem to make mine work.

what i want is for when one of the players (coop) sees the unit tank1, the trigger is activated.

i have tried making a trigger activated by vehicle (grouped with tank1) detected by west, and encompassing the area containing the tank and the players.

a step-by step from an expert is obviously required to sort me out here.

?(unit knowsabout tank1 >= .5): blablabla

[seldom]

i'd then have to do; unit1 knowsabout blah or unit2 knowsabout blah ad nauseum.

i know this isn't necessary from looking at softlanding.

Grouping the unit to the trigger should work. sample mission attached. put it in C:\Program Files\Codemasters\OperationFlashpoint\Users\YourName\missions

thanks very much... i assume from this demo mission that the group has to have waypoints, and then that waypoint has to be synchronised to the trigger?  thanks again.

Only the grouping to the trigger is required for detection, the sync to the waypoint was for checking that the conditions were met.
