Get Theme Options Not Working

So I followed the instructions of a tutorial on how to create theme options and at the part where you need to get the options, the code…

<?php
global $options;
foreach ($options as $value) {
    if (stripslashes(get_option( $value['id'] )) === FALSE) { $$value['id'] = $value['std']; }
    else { $$value['id'] = stripslashes(get_option( $value['id'] )); }
    }
?>

… is not working, unless I have everything in one file. So if I use header.php or footer.php and have this code in header.php, it will not replace the variables I have in my index file or in the footer. It only works if I call the same code in all 3 templates. Am I doing something wrong?
