BuddyPress.org

I have copied the default theme and modity it. I add some codes in the home page. (index.php) in the theme folder.
But when I add a input button “ and set it to the index.php, it can not run well.
such as first, the home page is http://localhost/wordpress/
When I click the input button ,the url change to :’http://localhost/wordpress/index.php’
And it show: ‘Sorry, no posts matched your criteria.’ and the index.php display not the first page, but a page like login statement page.
I copy the ‘http://localhost/wordpress/index.php’ to my new ie windows and open it, It also shows the original home page.
What is the reason, how to solve? Thanks.
