Hi Eoinyp, You have no navigation control added to your map.
map.addControl(new OpenLayers.Control.Navigation()); If you want use EPSG:26986, http://spatialreference.org/ref/epsg/26986/ shows the standard extent for that projection. You can't mix layers with different projections in one map. You declare a projection for your map and the layers will requested for this projection. OpenLayers can't reproject raster layers. In mymap2.html you should choose sphericalMercator (EPSG:900913) for the projection of the map. As you have choosen for the google layer. See the OL examples for the bounds of EPSG:900913 and resolution. You try to compound a map with three different projections. I think, the map projection is set to sphericalMercator by the google layer.

I have two simple wms layers being served by geoserver: a layer of US states, and a layer of town boundaries in Massachusetts. Each of the layers display fine on their own. Showing the full extent of the mapped area. When I put them both together however, only a section of the States layer is shown, while the full Mass layer is shown. It is not possible to pan and see the rest of the States layer. I am not entirely sure what the problem is, so im not sure how to fix it! The map with the states and the Mass towns layers here: http://www.eoinmaca.com/maps/OpenLayers/mymap3.htm I think it is a problem with the extent of the bounds of the layers defined. What should it be set to? currently it is: var bounds = new OpenLayers.Bounds( 19012.0201171875, 768402.5875, 345695.3353515625, 968859.1625); The layers have different EPSGs - is this a problem? The problem is compounded when I add in a googleEarth baselayer. It shows the full extent of the google layer, but when I zoom in I cant pan to the Mass area. The pan functionality seems to be constrained to a small area. The map with the google base layer is available here: http://www.eoinmaca.com/maps/OpenLayers/mymap2.htm If the bounds is the problem, is there a simple way of figuring out what the bounds of my map need to be?
