No problem, make sure you check out the scripting reference http://unity3d.com/support/documentation/ScriptReference/index.html whenever you get stuck.

You can try typing things in like “camera” or “world” or “screen”, you’ll get a fair few results but if you read them all I’m sure it’ll give you a hint of what you need to do.
