Help: Model Not Visible In Renders

I’m trying to make the transition from 2.49 to 2.5 and have fiddled settings. Now when I render I can’t see anything. What have I done wrong? The eyball has an outer “shell” that should be transparent.

In the render layers panel you first need to put a tick next to your renderlayer to select it and also you need to select at lease one of the passes such as combined.
