What you need is another file called process.php where PHP will save the data that you have entered. The issue you are having is not an HTML one, but PHP. You might take a look at
http://php.about.com/od/phpbasics/ss/mysql_files.htm to learn how to save the data in a MySQL database using PHP, which is how I would recommend saving the information.
Also,
method="get"slomatrix", what are you trying to do with the slomatrix" randomly added at the end there, it doesn't really fit / won't do anything.
