A trigger problem

How to make a wctory trigger
when one of my chracters is attacked or attacks then the battle start and the characters get teleported to the battle field
but how to make a victory trigger
When one of the fighting team has no units alive
when i select a event every 0.1 seconds and a requierment : number of unit n battle (region) owned by Neutrol Enemy equals to 0
Nothing happen what schould i do?
maybe it doesnt see that they are dead?

Try something like this

E - Unit on team1 dies
C - if (count units (owned by team1) = 0)
A - show victory for all team members on team2

Try this:

Events:
Generic Unit Event: An unit dies. (This removes any slowdown caused by a periodic trigger running ten times a second.)

Conditions:
Number of units in (battleRegion) matching (((Matching unit) is Alive) and (Owner of(Matching Unit) equal to Neutral Hostile) equal to 0

Actions:
Whatever is supposed to happen.
