Hi Guys  
I am making an Auto-Arrange button and clicking on which arranges all the children of the container( which are on the main stage) in the tile format. Basically on clicking, I manually move those child on the stage to particular coordinates as shown in my code. I have pasted my code below. My problem is that as soon as i click on the auto arrange button I am getting error “RangeError: Error #2006: The supplied index is out of bounds.”. Please let me know what i am doing wrong and i will appreciate if you let me know how would i fix this  
Thanks a lot guys
