Relative path for creating text field

programming flash
1

If I load txt a want to create text field and the assign the loaded vars to my txt field.
I can create the text field with absolute path **_root.createTextField **, but I would like to create this with relative path, how can I make it?
Now it works so:

//*********** LOAD VARIABLES ****************
myVars = new LoadVars ();
myVars.onLoad = function (success)
{
	if (success)
	{
		trace ("variables from txt file loaded FRAME 3!");
		// create text for menu ABSOLUTE PATH
		_root.createTextField ("menu1_txt", getNextHighestDepth (), 17, 15, 90, 18);
		//
		menu1_txt.text = this.var_menu1;
		menu1_txt.border = true;
		menu1_txt.selectable = false;
		menu1_txt.setTextFormat (myTF_fmt);
		menu2_txt.text = this.var_menu2;
		menu3_txt.text = this.var_menu3;
		menu4_txt.text = this.var_menu4;
		menu5_txt.text = this.var_menu5;
		menu6_txt.text = this.var_menu6;
		menu7_txt.text = this.var_menu7;
		menu8_txt.text = this.var_menu8;
		menu9_txt.text = this.var_menu9;
	}
