Columnize plugin not making columns...

Columnize plugin not making columns...

I am using the columnize plugin v1.4 and jquery v1.3.2 and cannot figure out what I am doing wrong. 

My css for the column div, etc is as follows:
/*columnize code*/
#middlePeopleSection {float:left;width:585px;height:460px;max-height:300px;padding:0;margin:0;background:yellow;}
#columnSection{float:left;width:580px;height:460px;margin-right:1em;background:#990000;}
.column{margin-right:1em;}
.first,.last{clear:both;}

p.people {text-align:left;font-family:"Times New Roman",times,serif;padding:0;margin:0;margin-bottom:20px}

The link to my test file is www.nasharch.com/test/people_columnizeTEST.php.

My objective is to have TWO columns of equal width.  I want the first column to be full width with everything that doesn't fit into the first column flowing into the second column.

Any help will be greatly appreciated!  Thank you!
