4 side by side widgets in footer

I am trying to alter the code to give me 4 side-by-side widgets, but I can't seem to get it to work.

This is the code I am trying:

<?php bfa_widget_area('name=footer_widgets area&cells=4&width=800&before_widget=<div id="%1$s" class="footer-widget %2$s">&after_widget=</div>'); ?>
