Stencil Help

I have been doing tutorials trying to get a better understanding of how everything works in Blender. One thing that I’ve run into is the Stencil option in the “Map To” Tab. Following this tutorial: http://feeblemind.tuxfamily.org/dotclear/index.php/2005/02/27/16-didacticiel-usage-des-masques-de-textures---tutorial-using-texture-stencils I can not get this to work. Now, in the comments section, someone posted that in v2.45, the stencil option does not work. Is this true? If so, how do I go about blending two materials to get a similar outcome? Thanks.

For some reason it was not working before but now it is. Sorry for posting.
