Auto Focusing a Nikon?

Somehow, I think I turned the auto focus off on my Nikon 3000. Can anyone tell me how to make sure it is on?

The manual can. I can give you a jint, it's an A/M switch

There are two areas to check.

On many lenses, there's an auto/manual switch. Make sure it is in the auto position.

And there's a focus selector in the menus. Make sure that is also set at autofocus.
