Parse error when widgetizing theme

I am trying to widgetize a theme using the techniques described at this site . I modified the original format of the sidebar.php file to utilize good sidebar markup as described in the above page and it works great.

I created the functions.php file and added the following into that file…

<?php
if ( function_exists(‘register_sidebar’) )
register_sidebar();
?>

When I add the following code to my sidebar.php file it creates a parse error…

<?php if ( !function_exists(‘dynamic_sidebar’)
|| !dynamic_sidebar() ) : ?>

Any ideas on how I could fix this or where I could look for additional information?

Thanks in advance,
Steven
