Error 1502

Error in this code…

Error number 1502

I dunno how to solve this sets of codes.
Error occurs in the for loop.

For loop code:


for(var i:int = prevCount; i < count; i++)
			{
				if(i <= 8)	
				{
				apple.x=Math.random();
				addChild(monkey);
				}
			}

i got another set of for loop whereby i set it as var r the rest is of a different objects called orange

For loop code:


for(var i:int = prevCount; i < count; i++)
			{
				if(i <= 8)	
				{
				orange.x=Math.random();
				addChild(monkey);
				}
			}

If anyone out there can help me solve the code, kindly leave your email in the reply thread and i will send u my set of codes to solve the error.Thanks alot.
