Transfer Data from Pop-up to Main Page
 

Can I transfer some data, which the user enters into a pop up window, to the page which called the pop-up window ? The Main page is in a frame. When the user clicks a button on the main page, a pop-up opens showing some choices. After the user selects the choice from the pop-up, the pop up is closed automatically and the main page shows the user's choice.

Can this be done using ASP/Javascript ?
