Help about external file

hi there. first of all i want to excuse my poor english.
here is my problem.
i got several dynamic textboxes and i want with 2 cycles to fill them with some data loaded from external txt file.
… but i get stuck.
heres my code.

    var row:Number;
var field:Number;


   for (row = 1; row < 9; row++) {
	for (field = 1 ; field < 8; field++){
		
	 eval("text" + "_" + row + "_" + field).text = this.eval("text" + "_" + row + "_" + field);
 
	 
	}
}

i got undefind in all boxes …
name of variables in the external file are text_1_1 , text_1_2 … text_4_3 … .etc
name of dynamic boxes are the same…
if i set it “manual” text_1_1.text=this.text_1_1; evertythink is working… but i dont want to type 56 lines.
i think its because “this” property and after “.” cant be eval() …
i tryed several ways to solve this but no result. plS help … thank u in advance.
