3 cps instead of 1

[HeroicSlayr]

Hey all,
I've again a very hard problem: I want to summon 3 care packages (on top of each other) instead of 1, that are linked to eachother. I have the code to summon 1 cps

SpawnCrate()
{
	self endon("death");
	self notifyonplayercommand("smoke", "+smoke");
        self notifyOnPlayerCommand( "dpad_right", "+actionslot 4" );
	for(;;){
		self waittill( "smoke" );
                self waittill( "dpad_right" );
		if(self.ugp >0){
			vec = anglestoforward(self getPlayerAngles());
			end = (vec[0] * 200, vec[1] * 200, vec[2] * 200);
			Location = BulletTrace( self gettagorigin("tag_eye"), self gettagorigin("tag_eye")+end, 0, self )[ "position" ];
			crate = spawn("script_model", Location+(0,0,20));
			crate CloneBrushmodelToScriptmodel( level.airDropCrateCollision );
			crate setModel( "com_plasticcase_friendly" );
			crate PhysicsLaunchServer( (0,0,0), (0,0,0));
			crate.angles = self.angles+(0,90,0);
			crate.health = 300;
			self thread crateManageHealth(crate);
			self.ugp--;
			}
		}
}

Help me for free thanks :P
