Awsome that worked there was one thing missing but I figured that out. No I have another question I would like to use this same style sheet for multiple pages so I figured I could use is_pages(array()). The code is below, the only thing is that the style sheet will not apply to any additional pages accept for forum.php.
<?php if ( is_page(array('Forum','Shopping')) ) :?><link rel="stylesheet" href="<?php bloginfo('template_directory'); ?>/wide.css" type="text/css" media="all" />
<?php else :?><link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); ?>" type="text/css" media="all" />
<?php endif;?>
So like I said I am a beginner at all off this, where would I add the code in the header.php file where it calls the rest of the style sheets. Or should I add it into the actual forum.php file?
