What settings do I need for a stop motion on a Nikon D3000?

I go to the menu and when I scroll over stop-motion movie it says that option is not available with my current settings. I just need to know what to change, thank you!

The way this works: you can take up to 100 images and put them together to make a movie. If you don't have images on the card or if you don't have sufficient space on the memory card, you can't access the option.

So, take up to 100 images *first* and then try the menu.
