[OpenLayers-Users] Simple KML layer help

Instead in- and externalProjection you can use projection in the layer
options.

var l =  new OpenLayers.Layer.Vector("KML", {
    strategies: [new OpenLayers.Strategy.Fixed()],
    projection: new OpenLayers.Projection("EPSG:4326"), //projection of the
data
    protocol: new OpenLayers.Protocol.HTTP({
        url: "test.kml",
        format: new OpenLayers.Format.KML({
            extractStyles: true,
            extractAttributes: true,
            maxDepth: 2
        })
    })
});

Arnd,

Thanks. I made your change and it works. Gesh, Looked at that forever. 
Is the code correct otherwise? Seems like I may have done unnecessary things
while trying to sort this out.
