Could someone help me correct my code to fit the instructions in the picture attached ? I'm not sure why my code isn't executing as the instructions says it should. Below is a copy of my code as well.

var runner = new Array(6);

var currunner = 0;

var begin;

runner[0] = new Image();

runner[0].src = "runner0.jpg";

runner[1] = new Image();

runner[1].src = "runner1.jpg";

runner[2] = new Image();

runner[2].src = "runner2.jpg";

runner[3] = new Image();

runner[3].src = "runner3.jpg";

runner[4] = new Image();

runner[4].src = "runner4.jpg";

runner[5] = new Image();

runner[5].src = "runner5.jpg";

function turn() {

if (currunner == 5)

currunner = 0;

else

++currunner;

document.runner.src = runner[currunner].src;

}

function startTurning() {

if (begin)

clearInterval(begin);

begin = setInterval("turn()",400);

}

onClick="clearInterval(begin);">
