need help to include my plugin updates under trunk

I have updated ‘my-simpletubes’ to version 7 but it only appears under the tags but no change happen inside the trunk. Please help me to move both the files (my-simpletubes.php and readme.txt) inside tags/1.7 to my-simpletubes.php and readme.txt under the trunk. You will see more than two files, that is because I think we need a second file (my-simpletubes2.php) in order to update it instead of change it directly inside original file, that happen during my first time using the svn, sorry about that. As for the version (now at 7), also have something to do with my previous mistake. So please just use version 7 now. Thanks.
