var urlString = "contact_confirm.php";
urlString += "?first_name="+first_name; (this is actually much longer with more data)
//This launches a new window and then
//focuses it if window.focus() is supported.
newwin = window.open(winurl,winname,winfeatures);
//delay a bit here because IE4 encounters errors
//when trying to focus a recently opened window
Thanks for any help!!
