[OpenLayers-Users] WMS Example Problem

[Andreas Hocevar]

Hi,

when using WMS layers, it is always a good idea to look at the
GetCapabilities response. In this case, this would be
http://geodaten1.graz.at/ArcGIS_Graz/services/Extern/BASISKARTE_WMS/MapServer/WMSServer?SERVICE=WMS&REQUEST=GetCapabilities

Looking at it, you'll see that layer "3" is just a line with the city
border, and "1" is the base map. So instead of configuring your layer
with

    {layers: '3'}

you will probably want

    {layers: '1,3'}

See this fiddle for a working Graz map based on your code:
