CS4 error 1061: .....undefined method addEventListener

I am new to CS4 and coding. When I test my movie it keeps going through my pics as a slide show. I just want the large pic to stay still and change when i click on my thumbnail size pics. What I noticed is that addEventListner should be blue and is not. Please help and here is my code:

stop();

button1.addEventListner(MouseEvent.CLICK,showpic1);
button2.addEventListner(MouseEvent.CLICK,showpic2);
button3.addEventListner(MouseEvent.CLICK,showpic3);
button4.addEventListner(MouseEvent.CLICK,showpic4);
button5.addEventListner(MouseEvent.CLICK,showpic5);
button6.addEventListner(MouseEvent.CLICK,showpic6);
button7.addEventListner(MouseEvent.CLICK,showpic7);
button8.addEventListner(MouseEvent.CLICK,showpic8);
button9.addEventListner(MouseEvent.CLICK,showpic9);
button10.addEventListner(MouseEvent.CLICK,showpic10);
button11.addEventListner(MouseEvent.CLICK,showpic11);
button12.addEventListner(MouseEvent.CLICK,showpic12);
button13.addEventListner(MouseEvent.CLICK,showpic13);
button14.addEventListner(MouseEvent.CLICK,showpic14);
button15.addEventListner(MouseEvent.CLICK,showpic15);
button16.addEventListner(MouseEvent.CLICK,showpic16);
button17.addEventListner(MouseEvent.CLICK,showpic17);
button18.addEventListner(MouseEvent.CLICK,showpic18);
button19.addEventListner(MouseEvent.CLICK,showpic19);
