Simple Jass Trigger not working

[Shadow]

function ChangeColor takes nothing returns nothing
    call SetUnitColor( GetEnumUnit(), PLAYER_COLOR_GREEN )
endfunction

function ZhugeLiang takes nothing returns nothing
    call ForGroup( armies_Army[5], function ChangeColor )
endfunction

//===========================================================================
function onInit takes nothing returns nothing
    local trigger t = CreateTrigger()
    call TriggerAddAction( t, function ZhugeLiang )
endfunction

Trying to make it so on initialization every unit in the unit group armies_Army[5] changes there color to green. I assigned all the units in a separate trigger. I know the problem is in this trigger posted above.

call TriggerRegisterTimerEvent(t,0,false)
u forgot about trigger itself
