[OpenLayers-Users] Adding a Mapserv Layer

Sat Nov 17 15:06:47 EST 2007

hi, you're never telling the map to draw.
i just went to your site and ran:
map.zoomToMaxExtent()
in firebug. then i get pink tiles. viewing one of them gives this error.

msLoadMap(): Unable to access file. (\home\yancho\public_html\nc\sample.map)

which probably means the webserver doesnt have permission to read that file.
