[OpenLayers-Users] JavaScript error: bounds has no properties

[Tom]

Arjen,

This is what I use for British National Grid and it works fine.


<script type="text/javascript">
var map;
function init()
{
var options = {isBaseLayer:true,resolutions:[72,36,18,9.6,4.8,2.4,1.2,0.6,
0.3,0.15,0.125], maxExtent:new OpenLayers.Bounds(0,0,2000000,2000000),
maxResolution:'auto', units:'meters', projection:'EPSG:27700', controls:[]};

map = new OpenLayers.Map( $('map'), options );
var layer0= new OpenLayers.Layer.WMS('Mastermap', '
http://somewhere/script.asp?',{layers:'topo_area,carto_text<http://somewhere/script.asp?%27,%7Blayers:%27topo_area,carto_text>',
format:'image/jpeg'});

map.addLayers(layer0);

map.setCenter(new OpenLayers.LonLat(543443,255213), 7);
}
</script>

cheers,

Tom
