Addon Domain help

[Harry122]

I have my regular Bluehost site, let's call it "johnsmith.com" :D

I recently created an Addon Domain, and bought the name "harry122.com."

Right now, I'm redirecting harry122.com to johnsmith.com.

I also have a folder within my site called harry122.

Is there a way for me to set up a folder so that when someone goes to harry122.com, they go to that folder, and the address bar at the top of their browser reads "harry122.com?"

I'm guessing that this is kind of a newbie question, so thanks for the patience!

in the control panel, go to "addon domains"

type in the url of the addon domain, and a name for the directory. click "Add Domain!".

its that simple.
