Error in theme The Source from Elegant themes slider position

I have theme The Source from Elegant themes. But the featured slider do not center. It go to left by start the site. So i have this error make. In the featured.php have you position top, center, no-repeat, zie php script from the featured.php

<div class="slide" style="background: #<?php echo($bgColor); ?> url('<?php print_thumbnail($thumb, $thumbnail["use_timthumb"], $titletext, $width, $height, '', true, true); ?>') top center no-repeat;">

[Please use the code buttons or backticks when posting code]
