Why do I have no power steering

What is your question?

I got a question for a mechanic. My car initially had no power steering so I changed the pump, flushed the system, added new fluid and bled the air and still have none. The guy from the store told me I could use a certain type for my power steering but the fluid was the wrong stuff so I flushed it all out again, added the right fluid, And did the same process over and still got nothing.
