One Click worpress install issue

So just a quick question to see if what I suspect is true. Im set up with the Dreampress service for a blog I am working on. I have a “FULLY” hosting type under the domain I listed. However when I go to do my one click install for wordpress Im not seeing the domain in the drop down menu. I tried typing into empty box to the right and get a please type the correct url message. The domain is hosted elsewhere. Is this just a matter of waiting on the DNS to update or am I missing something else. Be gentle as this is my first foray into web hosting. Thanks in advance.

Enabling DreamPress for a domain automatically creates a WordPress install. Wait for DNS to update and you should have a site waiting for you.

Thanks for your reply. Will wait as instructed. You can lock this up or delete if needed.
