[SOLVED] Correct Code to Align Cells in new 4 Column Widget Area Created in Footer

Hi,

Using Atahualpa 3.6.4 and WordPress 3.1.4, I have used the following code in the ATO > Style and Edit Footer box to create a new four-column widget area in the Footer:

<?php bfa_widget_area('name=Footer 4Col Widget Area&cells=4&align=8&align_2=8&align_3=8& align_4=8&before_widget=<div id="%1$s" class="footer-widget %2$s">&after_widget=</div>'); ?>

It works, but I'd prefer to have the columns aligned so that the far right and far left columns are the same width as the right and left sidebars on the site (220), and the center two columns should each occupy half the width of the center column (which expands). I have the site set to expand, with a fluid width of 90%, a minimum total width of 940, and a maximum width of 1000.

Can someone give me the exact code to create the new footer widget area with that alignment and width? I'd be very grateful! (Sorry, but I don't really understand the instructions on the ATO > Create New Widget Area page. The example code they have there for creating a four column widget area did not seem to work at all.)

Many thanks!
