Hello, I try to specify the layer array like this "map.layers[2,3,4,5]" but that does not work. Is this correct? I always get popups only on the last layer I have specified. Is my way of specifying the layers array correct? How do I check what version of OpenLayers I have? A lot of questions! Thanks.
