Labels and slideshow

programming flash
1

Hi,
I have a slideshow and four menu buttons. btn_k1,btn_k2,btn_k3,btn_k4.
I labels- one, two, three, four.
When you click on btn_k1 it is supposed to go to label one. and so on.
I have this script. I doesn’t work. What do I do wrong. Do you ave any ideas?
Thank you

this.addEventListener(MouseEvent.MOUSE_DOWN,btnscript);

function btnscript(e:MouseEvent){

if(e.target.name=="btn_k1"){
    gotoAndPlay("one");
    }
    
    if(e.target.name=="btn_k2"){
    gotoAndPlay("two");
    }
    
    if(e.target.name=="btn_k3"){
    gotoAndPlay("three");
    }
    
    if(e.target.name=="btn_k4"){
    gotoAndPlay("four");
    }

}
