I've created a rectangle, and I want to cut some text out of it, so that the text will appear as the background pattern. 

I expected to be able to achieve this by selecting the rectangle and the text, using `Pathfinder > Minus Front` - however this hasn't worked. I've tried searching for the solution everywhere and can't find an answer.

Can anyone tell me where I'm going wrong?
