Patience; a new website can take 12-48 hours to propagate through the DNS servers of the Internet.
You can cheat, however - using the DNS section of the control panel you can find the numeric ip address of your site's "www" entry and enter it in your local PC's "hosts" file. IN MS Windows, this file is usually under C:\WINDOWS\system32\drivers\etc folder - make sure it's called "hosts" and not "hosts.sam" (...the "sample" file) or "hosts.txt" (which MSNotepad will try to make).
For example, put a line in it that reads:
..where the 220.127.116.11 is the actual ip address from the DNS contrpl panel and the www.tozzie.com is your website name.
If that's too complex, then you just hafta chill until tomorrow.
