Hi,
usually when you do not get a reply to a question within a day, then
there is probably information missing that would allow for quick
examination of the problem. So just re-posting the same question may
not be the best way to get a reply.
In this specific case, we know that you are using the hosted version
of the OpenLayers API, but we have no idea what hides behind your
openlayers_scalebar.js and css/scalebar.css.
Anyway, a quick glance at your code shows me that the units property
of the map should not be "meters", but "m". Maybe changing this will
get you somewhere.
Also, if you use a single file build of OpenLayers, you should also
add the theme/default/style.css stylesheet to your webpage.
Regards,
Andreas.
