Applying more than 1 action to a frame

Hi, hope someone can help me, I am using action script 3 and need to know how to apply more than 1 action to a frame label, ie; I have 5 pages of images and have actions coded as follows:

btn1.addEventListener(MouseEvent.CLICK,play1);

function play1(event:MouseEvent):void{
gotoAndStop(“1Lrg”);
}

btn2.addEventListener(MouseEvent.CLICK,play2);

function play2(event:MouseEvent):void{
gotoAndStop(“2Lrg”);
}

btn3.addEventListener(MouseEvent.CLICK,play3);

function play3(event:MouseEvent):void{
gotoAndStop(“3Lrg”);
}

btn4.addEventListener(MouseEvent.CLICK,play4);

function play4(event:MouseEvent):void{
gotoAndStop(“4Lrg”);
}

code continues like this for all the buttons (84 thumbnail images), so they will open a larger image when clicked. So what I now need to do is connect the side navigation buttons to go to the relevant page (frame) when clicked…the problem I’m having is that it is causing duplications in the code ie; I now have, for instance thumbnail (btn4) calling frame 4, but I also need a side navigation button to call this frame. Hope this is clear enough to understand, would really appreciate someones help.:smiley:
