Sending Data when click

Hello,

I am wanting to send data from my popup to a input box in it's paren'ts window.

The data that I'm wanting to send is the id number of the row that's clicked on.

Is this possible? And if so, how?

Thank you so much for your help!
Travis

try this

window.opener.document.getElementById("yourInputBox").value = "id fromPopupWindow";
