How to get the values of a textarea from popup window to textarea in parent(opener) window using javascript.

I used

Could you post some code you allready have? Especially the part
where the value from your popup should be grabbed and pushed into
the parent texarea.

I'm no js expert but maybe you just have to change the left with the
right part of your code. Basically your line tells the popup textarea
to grab the value of your opener value.
