Is it possible to pass selections from a pop-up window to a main page with JavaScript? On the following page http://www.cbshome.com/IRP/listing/ListingSearch.asp?ListingType=1&SearchType=Geographic a map link provides a pop-up window with a map. When you click on sections of the map, the information of the selection is passed back to the main page. How is this done? I've got a file with a map that fills in form data when a selection is made, but it is all on one page. I like the pop-up idea. Can't seem to understand how they did it? Anyone have experience with this? Thanks, Greg
