Moving Items.

I'm making a game with moving targets however I'm not quite sure on how to make them move on the start up on the level. I have them moving if i manually call the item ID and call the function but i want the targets to be moving once the level loads.

Here is my Code.
****Target Item****
$jTarget1= new Item(Target) {
canSaveDynamicFields = "1";
Position = "416.658 256.389 220.276";
rotation = "0 0 1 90";
scale = "1 1 1";
dataBlock = "Targets";
collidable = "1";
static = "1";
rotate = "0";
};

****Moving Function****

//Goes back and forth 2 units every 4 seconds.
function movemeleft(%object){

%x = getword(%object.getposition(),0);
%y = getword(%object.getposition(),1);
%z = getword(%object.getposition(),2);

%newx = %x-2;

%object.setTransform(%newx SPC %y SPC %z) ;


schedule(400,0,"movemeright",%object);
}

function movemeright(%object){

%x = getword(%object.getposition(),0);
%y = getword(%object.getposition(),1);
%z = getword(%object.getposition(),2);

%newx = %x+2;

%object.setTransform(%newx SPC %y SPC %z) ;


schedule(400,0,"movemeleft",%object);
}



I feel i should just be able to call movemeleft($jTarget1); and have it move left to right that on launch but when i run it it doesn't move the target. Any insight would be much appreciated.
