Hello,
I'm just trying to display a map, my service has 51 layers of different maps on it and I want to display just a certain layer, i was wondering how that is done. I know how to display the map with all the layers at once but I can't active it with just certain layer on. if any one know how I can do this and can tell me that would be Awesome. if you need more info or I wasent clear please let me know so I can try ex-plane better.

Assuming you're working with a dynamic map service, you want setVisibleLayers(): http://help.arcgis.com/en/webapi/javascript/arcgis/help/jsapi/arcgisdynamicmapservicelayer.htm#setVisibleLayers
