Multiple Widget Sections in a Theme

So I’ve successfully implemented two widget sections in a theme, but a third does not seem to be working? I can’t seem to drag & drop a widget into the third section I created and I can only assume it’s something I did wrong in the php.

My functions.php file looks like this…

<?php
if ( function_exists('register_sidebar') )
register_sidebar(array('name'=>'Available',
));
?>

<?php
if ( function_exists('register_sidebar') )
register_sidebar(array('name'=>'Recent Photos',
));
?>

<?php
if ( function_exists('register_sidebar') )
register_sidebar(array('name'=>'Shows',
));
?>

Here is the theme I’m working on…
