Whats wrong with my camera?

On one of my scenes that I have made for my animation, I have added a camera but when I look through the camera view it looks through a camera but with dotted lines instead of the camera that I have just added. That is the only camera within the animation and I have checked all other layers for any other ones. There are no hidden objects on the file and when I press CTRL ALT 0 to change the camera to my view it changes the dotted line thing which looks like this:


The dotted lines show you the passpartout (french i think for "everything that passes through) - the field of view (the outer lines) which is what will be rendered and the title-safe area (the interior box).
