Thanks, Jamie. If I could possibly understand it --which I doubt, my javascript being limited mostly to what I can copy and paste-- your suggestion might work if I was just generating *one* polyline, but I'm trying to replicate KML functionality. That is, create a bunch of polylines and polygons that are going to be shown and hidden as a group, a "category" in an array.
This exercise comes from my problems trying to create tiny polygons from a KML file: http://groups.google.com/group/Google-Maps-API/browse_thread/thread/85500436cbc38279# I just can't face tearing up the whole map to get a few polylines and polygons working! I've looked at a hundred different codes from links in this forum, tried a dozen different ways to simply add a few polylines and can't get anything *simple,* that will work with my markers the same way they do, so that I can have my polys listed in my sidebar and show and hide them as a group/category. Maybe this will never work! Thanks, though, for considering my problem.
