Basic question, making me go bald

Question

I am trying to get some buttons to communicate with some movie clips. Specifically, I want button 1 to tell movie clip 1 to move, button 2 to tell movie clip 2 to move, etc. If I hard-code it, I have no problems. But this is, as a friend used to say, an inelegant solution.
Here's the code as it stands.
If I test the movie, ALL the clips move in at once. I have been searching online forums and have found nothing.
Could I please ask for some help?
Thanks!
import flash.events.MouseEvent;
import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;
var btnArray:Array=[button1_btn, button2_btn, button3_btn, button4_btn];
var mcArray:Array=[art1_mc, art2_mc, art3_mc, art4_mc];
for(var j:int=0; j < btnArray.length; j++)
    btnArray[j].addEventListener(MouseEvent.CLICK, shiftImage);
    function shiftImage(event:MouseEvent):void
            for (var k:int=0; k < mcArray.length; k++ in mcArray)
            var shiftThing:Tween=new Tween(mcArray[k], "x", Elastic.easeOut, 550, 160, 1, true);

Here's one way to do it... assuming you do not want to move all of the movieclips like your code was trying to do.  You do not want to bury the function in a loop.
import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;
var btnArray:Array=[button1_btn, button2_btn, button3_btn, button4_btn];
var mcArray:Array=[art1_mc, art2_mc, art3_mc, art4_mc];
function shiftImage(event:MouseEvent):void
var mc:MovieClip = mcArray[btnArray.indexOf(event.currentTarget)];
var shiftThing:Tween=new Tween(mc, "x", Elastic.easeOut, 550, 160, 1, true);
for(var j:int=0; j < btnArray.length; j++)
    btnArray[j].addEventListener(MouseEvent.CLICK, shiftImage);
