Event.Target issue

Question

Hi, I think I wrote this wrong but can't find a solution.
This works:
Parts1_mc.addEventListener(MouseEvent.CLICK, RunTraining);
function RunTraining(e:MouseEvent):void
Global.run = Parts1_mc.Parts1.text;
trace(Global.run);
When I do this, I get a undefined error message:
Parts1_mc.addEventListener(MouseEvent.CLICK, RunTraining);
function RunTraining(e:MouseEvent):void
Global.run = Parts1_mc.event.target.text;
trace(Global.run);

Simpler is a relative thing, so I may miss since my understanding of this is also simple (more of an acceptance than an understanding)... greater minds might prevail here with a better explanation (or possibly a more confusing one).
From what you just quoted, the simplest way of stating part of it was just as it is stated...
     “currentTarget” is the Movieclip (object) that you applied the listener to.
So if you assigned the listener to Parts1_mc, the currentTarget of the event is Parts1_mc.  That will not vary.
But Parts1_mc contains other objects, in your case a textfield, which is an interactive object and if interacted with will trigger the event.  Since it is a child of Parts1_mc it still gets detected by the listener that is assigned to Parts1_mc.
You should go thru the explanation you linked and try to see how different elements can end up being the target under different conditions.  That same link is where I was going to point you to to explain things.
Another thing you could do is just create a simple movieclip object (named container below) that contains various different types of objects.... a button, a movieclip, a dynamic textfield, a static textfield, a raw shape... and use the code below to see what comes up each time as far as currentTarget and target go...
container.addEventListener(MouseEvent.CLICK, showTargets);
function showTargets(evt:MouseEvent):void {
    trace(evt.currentTarget.name);
    trace("     "+evt.target.name);
Sometimes you will see they both identify the same object (the container), but other times the target will be different.
The "target" property of the event can end up being helpful in different scenarios, such as if you have a drop down menu.  You can assign the listeners to the parent movieclip to make coding the rollover/rollout functionality a quick couple of lines, and then use the target to determine which button within was clicked.  Beats the hoops one usually jumps thru when making a drop down menu in AS2.
If the intention is to manipulate the object that has the listener assigned, then using currentTarget will always point you there.
