Help removing a symbol then adding it in a different place

Hi, i am currently trying to write code, so if i enter a value into a textbox it will move a symbol up and down the screen according to the value. I was using the method of removing the child at for example removeChildAt(1) then deleting it and re adding it in a different place. But for some reason as i have 10 symbols and textboxes it kept deleting random things. So i decided to try remove child by name, but this still hasn’t worked could anyone help me? Here is my code.

// EXAMPLE WHERE TEXTBOX USED TO POSITION A BALL ON THE STAGE
package 
{
	import flash.display.Sprite;
	import flash.display.Stage;
	import flash.text.*;
	import flash.events.*;

	public class testScript extends Sprite
	{
		// text boxes for rating

		private var myTextBox7:TextField = new TextField();
		private var myTextBox8:TextField = new TextField();
		private var myTextBox9:TextField = new TextField();
		private var myTextBox10:TextField = new TextField();


		// text in the text boxes
