Hi Eoinyp,
<br><br>I watched your code. I think you made a mistake with the zoom level on the function map.setCenter().
<br><br>Try to modify the line like that:
<br>map.setCenter(new OpenLayers.LonLat(17, 43), 12);
<br><br>It should work ;)
<br><br>Here is the copy of your code that I used and modify:
<br> map = new OpenLayers.Map("map");
<br> map.addControl(new OpenLayers.Control.LayerSwitcher());
<br>
<br> //create layer
<br> var velayer = new OpenLayers.Layer.VirtualEarth(
<br> "Roads Layer",
<br> {
<br> 'type': VEMapStyle.Road
<br> }
<br> );
<br>
<br> var velayer2 = new OpenLayers.Layer.VirtualEarth(
<br> "Aerial Layer",
<br> {
<br> 'type': VEMapStyle.Aerial
<br> }
<br> );
<br><br> map.addLayers([velayer, velayer2]);
<br><br><br> map.addControl(new OpenLayers.Control.PanZoomBar());
<br> map.addControl(new OpenLayers.Control.ScaleLine());
<br> map.addControl(new OpenLayers.Control.MousePosition());
<br><br><br> map.setCenter(new OpenLayers.LonLat(17, 43), 12);
<br><br>Sincerly,
<br>Jérome

<div class="quote-message shrinkable-quote">Im a newbie, having problem with my map layers. Which ever layer I add first is visible when the map loads, but when I try to switch layers they both disappear. I seem to be missing something fundamental, though I cant figure out what!!
<br>I am creating the layers and map as follows:
<br><br> init(){
<br>create layer 1
<br>create layer 2
<br>add([layer1,layer2])
<br>add[map controls]
