The problem is that you are not specifying a page in your URLs (or action part of form). When installed in the root directory leaving this part out tells the server to use the default page for the directory. This is how the server is able to display your home page when you enter just your URL: ie http://skinbonestone.com/ instead of http://skinbonestone.com/index.html.
My advice is to reinstall into a sub directory. That way the WP index page can be the default page of that sub directory.
IS this installed with the index.php for Word Press in the same directory as your home page? If so, the server is acting as it should. In your code your action is not specifying a page, so the default one for the directory will be used. If this is the case, change the action to ACTION=”index.php?page_id=40″ and it should work. The way you have it coded should work if WP is installed in it’s own sub directory.
