Jeff, Go ahead and post your mapfile (or the 4 relevant layers) to the listserv. Also, try to remember that the openlayers listserv defaults to having the reply-to address be the poster, not the listserv, so you have to hit "reply-to-all" to get it to go to the listserv.

You did not include your options variable in the code you posted, are you saying this does not have a projection specified? Also, make sure that the countries layer has it's projection specified in the mapserver layer. You might want to go ahead and post up your mapfile as well. r.b. Robert W.

Commenting out "rivers" and "cities" layers and running only the "countries" layer had, as expected, only the "countries" layer in the layer switcher, but when selected, the "countries" layer does not display. The projection information passed in with the "countries" layer matches the MAP projection information as well as the base raster layer projection information. Oddly, the "rivers" and "cities" layers have different projections than both the base raster layer and the "countries" layer. All these layers display when MapServer combines the layers together. I may need to pass in a projection parameter with OpenLayers, yes?
