Tooltip for flash map is misbehaving

Question

I'm creating a cool flash map with close to 70 locations
listed. I created a tooltip function that displays the tooltip when
the user rolls over any location button on the stage. Now, I would
like to know what is the best way to inject the tooltip info
dynamically in my function. So far I have this(see attached code
below) and the tooltip function works but the array info is not
displayed correctly. I get an "undefined" in the tooltip text area
when I roll over the location. What could I be missing?
Any help is much appreciated. Gracias!
function showTip(tipText, orient) {
tooltip._x = _xmouse;
tooltip._y = _ymouse;
tooltip._visible = true;
tooltip.gotoAndStop(orient);
tooltip.tiptext.text = tipText;
tooltip.tiptext2.text = tipText;
onMouseMove = function(){
tooltip._x = _xmouse;
tooltip._y = _ymouse;
updateAfterEvent();
function hideTip(){
tooltip._visible = false;
var b69_text:String = "Espies \n90 Wythe Ave.";
var array_text:Array = new
Array("location0","location1","location2","location3");
for(i=0; i<5; i++){
this["b"+i].onRollOver = function(){
showTip(array_text
, 5);
this["b"+i].onRollOut = function(){
hideTip();

I played with the code in every way I can think of, so to get
a reason as to what's being violated we'll need someone with expert
knowledge.
What it appears to boil down to is assigning the rollOver
function in a loop with any kind of variable in the showTip
function call won't fly, except for the case where it is as it
appeared in your posting (with the [ i ] absent)... in which case
the entire array displays. If I try to assign the current array
value to another variable, within the loop, ahead of defining the
function, and use that in the showTip call, it displays the last
element of the array for all cases.
In the event that no one who knows why comes into play,
there's another way that you can skin this cat... Place your
buttons into movieclips (right click->convert to symbol, etc),
and use the loop to assign the tip text to a variable in the
movieclip. Your button code within the movieclip can be the same
for all cases, calling on that variable.
