Seizing places

[7894rmnxj 10]

i have been wanting to create a mission where you have to take certain stragic places over the city and one you capture all of them with no enemy soldiers with in 100m of the zone then you win.

I have tryed using the triggers i.e.

activation "seized by bluefor"
Present, repeatdly
On Activation: Trigger_one =true; 

and then i created another trigger

 Activation: Trigger_one;
On Act End 1

however i have put an opfor soldier in it and its is still counting it as being seized any ideas which could help me

I really fail to see what this has to do with Configs and Scripting (addons) while you clearly talk about Mission editing.
