Is it actually taking the pictures? When you load new the film in it the camera should be reading a "1" if it's loaded correctly. When you go back to retrieve the film, if it has any number on the counter other than a "0" it needs to be rewound before you open it up. Also, alll the bateries need to be hooked up before you load up the film. You probably already know this but just checking.
