Iframe: Get textbox value from main page(opener)

[alpha_4762]

Hi!

 

I need help on how to get the textbox value of my main page that calls another window that has an iframe in it.

 

Note: There are 3 html/php file.

1 - The Main page or the caller/opener which holds the textbox

2 - The php/html file that holds the iframe (pop up window)

3 - The html/php for the iframe

 

I tried:

opener.document.getElementById("textbox_name").value;

 

Obviously I am not able to make it work since I'm asking for help.

 

Please help!!!
