Website URL – Help Needed

I am trying to install a Word Press on the address “kypha.net” through Network Solutions. When I do in the setup, you must choose a folder on your web site where you would like WordPress to be installed. When I go to the actual site, it doesn’t go to http://www.kypha.net. Instead it goes to http://www.kypha.net/website. How do I correct this problem? It may have to do with the Word Press or Site Address URL, Domain Names Pointing to the Package or something else. Please help me.
