Right now I have it set up so I can launch a page using javascript <a href="#" onclick="ST();hidePopupMenu();" >Mark Speed Trap</a> function RLC() { jsvar4 = addresscode; jsvar5 = citycode; jsvar6 = statecode; window.location = "../xx/xx.aspx?add=" + jsvar4 + "&city=" + jsvar5 + "&state=" + jsvar6 + "&lvl=2" } Code (markup): What I want to do is launch this same url with the query string in a modal using showModalDialog Method or something similar.
