This is javascript question. Imagine your textbox have id 'blabla'.

In your child window, your submit button must invoke this javascript question: top.opener.window.document.getElementById('blabla').value = the_new_value; window.close();

then you can just use window.document.getElementById('blabla').value = the_new_value;

I don't know the implementation of redbox. I assume redbox make "modal window" not using child window. So redbox page is same as in parent page.
