The easiest thing to do would be to keep a reference to the "one that the user has just added". Then do map.clearOverlays() which will remove all the overlays, then re-add the one you want to keep. The other option is to keep track of all of the polylines (perhaps in an array), and go through them calling map.removeOverlay on each of the ones that you want removed (but not on the one you want to keep). -- Larry > > Here is a link to the code: > > http://bil.ci.billings.mt.us/pwe/City_Projects/maps/Polyline3.asp > > When using the tool, you have to create a polyline then use the date > fields to check a date range of the polylines stored in a database. > > The polylines represent street closures or parade routes or stuff > happening in the streets....
