Help me with my particlesource

[lucilk 10]

I need some help with some script lines, i need this particle to spawn at 600 m height (altitudine), here is the particle:

_top = "#particlesource" createVehicleLocal [ getPosASL nukepos select 0, getPosASL nukepos select 1, (getPosASL nukepos select 2) + 600];
_top setParticleParams [["\Ca\Data\ParticleEffects\Universal\Universal", 16, 3, 48, 0], "", "Billboard", 1, 13, [0, 0, 600],
			[0, 0, 90], 0, 1.7, 1, 0, [90,95,100], [[1, 1, 1, -10],[1, 1, 1, -7],[1, 1, 1, -4],[1, 1, 1, -0.5],[1, 1, 1, 0]], [0.05], 1, 1, "", "", nukepos];
_top setParticleRandom [0, [75, 75, 15], [17, 17, 10], 0, 0, [0, 0, 0, 0], 0, 0, 360];
_top setDropInterval 0.002;
_top setParticleCircle [50, [-30, -30, 10]];

Thanks

this setPos [(getPos this select 0),(getPos this select 1),600];

tried putting this in the init field of the "nukepos" object?
