I have a website already up an running which was done by the friend of a friend...

I used Publisher 2003 to create my own and now want to publish it to the same web address I already own. I tried following the instruction but now when I go on the internet and type in my web address, the old page still comes up. What am I missing...to be honest I'm not familiar with alot of the terms being used but I can get around pretty good.

Thanks for any help
