Fluid simulator goes wrong?!

Hello there. I am trying to make a nice fluid fore more than two days now. But i cant get it right.

i know this. You need a Domain and a Fluid.

So i got two cubes. I used the standard cube and set it as the domain. I sized it a little bit bigger. Then i added a second cube. and shrinkt it a little bit down. And I used the second cube as the fluid. I put the second cube ( wich acts as the fluid ) inside the domain box. Then i click the domain agian and give it a bake directory. But when i do this. The domain becomes the fluid. So I get a big fluid cube with the second smaller cube inside that does nothing.

Anyone help please?

This is what you expect to see with the fluid sim. Here is the documentation for the fluid sim http://wiki.blender.org/index.php/Doc:Manual/Physics/Fluids
I suggest you watch some tutorials so you understand what is happening. Here’s one but just search on google or youtube and there are loads of examples.
