sending a echo to a different window

[talltyler]

hey I have a flash movie that has a link that makes a pop up that loads a php file. I need for that pop up to send a echo to that other page so that I can read it in flash.

I can handle the flash I just need to know how to send a echo to a different window. thank you

You can only communicate between windows with JavaScript.

And how do I do that. All I need is something to search for or a comand or one line of how someone has done this before. thanks for the reply
