TypeError: Error #1010: A term is undefined and has no properties.

Hi, I'm trying to make a game where the character "eats" candy. So when it collides with the candy, the candy in the array should disappear or be removed. Below is my code for removing. I keep receiving an error message that states "TypeError: Error #1010: A term is undefined and has no properties." Please help me. Thank you.

stage.addEventListener(Event.ENTER_FRAME, duplicateCandy);

var myCandies:Array = new Array();
var candyCount:int = 0;
var candySprite:Sprite;
//"candy" is the linkage name in the library
var myCandy:candy;

function duplicateCandy(candyEvent:Event) {
if (candyCount < 5){
candySprite = new Sprite();
stage.addChild(candySprite);
myCandy = new candy();
candySprite.addChild(myCandy);
candySprite.x = Math.random() * stage.width;
candySprite.y = Math.random() * stage.height;

candySprite.width = 50;
candySprite.height = 50;

var blnColorChange:ColorTransform = new ColorTransform();

blnColorChange.blueOffset = (Math.random() * 510) - 255;
blnColorChange.greenOffset = (Math.random() * 510) - 255;
blnColorChange.redOffset = (Math.random() * 510) - 255;

candySprite.transform.colorTransform = blnColorChange;

myCandies[candyCount] = candySprite;
candyCount += 1;
if(candyCount >= 1){
stage.addEventListener(Event.ENTER_FRAME,moveCandy);
}
}
}

function moveCandy(canEvent:Event){
for(var i:int = 0; i < myCandies.length;i++){
myCandies[i].x -= 10;

if (myCandies[i].x < 0){
myCandies[i].x = stage.width;
}
}

for (var k:int = 0; k < myCandies.length;k++)
{
if (myCandies[k].hitTestObject(om))
{
stage.removeChild(myCandies[k]);
myCandies.splice(k, 1);

}
if(myCandies[k].y > 400)
{
stage.removeChild(myCandies[k]);
myCandies.splice(k, 1)

}

}
}
