Search button width

[misty]

header.php file is missing line of code
your file shows

define('HEADER_SEARCH_DEFAULT_TEXT','Enter keywords here');
#logo {float: right;}//REMOVE

should be

// header Search Button/Box Search Button
define('HEADER_SEARCH_BUTTON','Search');
define('HEADER_SEARCH_DEFAULT_TEXT', 'Enter search keywords here');

Code marked red in your header.php should NOT be there..remove it
