Loader Won't Load on All Pages

Question

Hey everyone,
Here is my problem. I am creating a website that has four different pages with two different pages that load pictures into a loader. Right now, everything is loading fine, but when I go to the frames (i.e. other pages of the website) where the loader doesn't exist, and then I go BACK to one of the previous pages, the loader doesn't display anything when I press the buttons. The dynamic text box doesn't load either. I am using two different arrays to load it. Also, I had to put the Actions on the second frame of the whole scene for some reason. Is there some rule about having buttons on one frame load things into a loader that is on another frame?
I hope this makes sense. Thanks.
var myArray: Array = ["D1.jpg","D2.jpg","D3.jpg","D4.jpg","D5.jpg" ]
var desc: Array= ["Description1 ,Description2, Description3, Description4, Description5"]
var myArray2: Array = ["A1.jpg", "A2.jpg"]
var desc2: Array= ["Description1", "Description2"]
btn1.addEventListener (MouseEvent.CLICK, ldr1)
function ldr1(e:Event) {
    my_ldr.source = myArray[0];
    myTxt.text = desc[0]
btn2.addEventListener (MouseEvent.CLICK, ldr2)
function ldr2(e:Event) {
    my_ldr.source = myArray[1];
    myTxt.text = desc[1]
btn3.addEventListener (MouseEvent.CLICK, ldr3)
function ldr3(e:Event) {
    my_ldr.source = myArray[2];
    myTxt.text = desc[2]
btn4.addEventListener (MouseEvent.CLICK, ldr4)
function ldr4(e:Event) {
    my_ldr.source = myArray[3];
    myTxt.text = desc[3]
btn5.addEventListener (MouseEvent.CLICK, ldr5)
function ldr5(e:Event) {
    my_ldr.source = myArray[4];
    myTxt.text = desc[4]
abtn1.addEventListener (MouseEvent.CLICK, aldr1)
function aldr1(e:Event) {
    my_ldr.source = myArray2[0];
    myTxt.text = desc2[0]
abtn2.addEventListener (MouseEvent.CLICK, aldr2)
function aldr2(e:Event) {
    my_ldr.source = myArray2[1];
    myTxt.text = desc2[1]

my_ldr must exist on all frames or, if you navigate to a frame where it doesn't exist, you must create another loader with the "new" constructor.  in the later situation, you'll need to (re)define your button actions too because the new loader will need to before referenced in the button listener functions.  even if you use the same name, my_ldr, you'll probably need to re-define your buttons.
