<DIV>Hi Lucas</DIV>
<DIV> </DIV>
<DIV>A WMS server only sends back a finished map as a JPEG or PNG. You cannot then modify that image at the client end (OpenLayers). The StyleMap code is there for modifying vectors, such as a GML or WFS layer, where the vectors are actually rendered at the client end (Browser).</DIV>
<DIV> </DIV>
<DIV>I believe there is a way to send some styling information to your WMS server (Geoserver) using an XML SLD which is included as part of the GetMap call. Otherwise, you need to set up different layers on your WMS server with different styling, and call the appropriate one via the WMS GetMap calls.</DIV>
<DIV> </DIV>
<DIV>Hope that helps,</DIV>
<DIV> </DIV>
