Question : Passing value from one page textbox to another page textboxes

Hi,
I am newbie in web development specially in javascript. I've two pages, PAGE 1 and PAGE 2. PAGE 2 pops up when user click on PAGE 1 Button A or B. User can fill out ONLY one TextBox on PAGE 2(TextBox A or TextBox B).

If user click on PAGE1, Button A and then fill out anyone TextBox on PAGE2(Whether it is TextBox A or B), the value should populate on Page1, TextBox1. And the same way it works on Button B. I've the codes for both pages which is attached in .htm format.

Page1
 
 
page2.htm (1 KB) (File Type Details) 
Page2

			opener.document.getElementById( gup("target") ).value = document.getElementById('Page2_Txt1').value;
		}
		else if(document.getElementById('Page2_Txt2').value != "") {
			opener.document.getElementById( gup("target") ).value = document.getElementById('Page2_Txt2').value;
		}
		else {
