mist makes scene disappear

Support Compositing and Post Processing

I’m sure this is something simple that I’m doing wrong but I’ve been trying to make the mist work on a sample scene. Whenever I turn on the mist button in the world buttons when I render the scene its empty. I can turn off the mist and everything comes back. I’ve been looking at the instructions at http://wiki.blender.org/index.php/Manual/Mist but I’m not doing something right.
TIA

Its to misty and you cant see any thing.
from Wikki
Objects further from the camera than Sta+Di are completely hidden by the mist.

JUST turning on mist will not work. You need to change the mist-depth value, it is directly beneath the mist button. The larger the value, the ‘clearer’ the scene.
