IE versus FF padding?

If you look at this page in IE6 there is a gap on the right side of the left nav column. That does not appear in FF. I am referring to the space between the dark blue bottom border and the white pagebody content.

Here is the code:
.leftnav {font: 11px/11px Arial, Verdana, Geneva, Helvetica, sans-serif;
color: #333333;
padding: 3px 0 3px 0;
margin: 0 5px; 0 5px;
border-bottom: 1px solid #6ec1dc;
}
.leftnav a{color: #333333; text-decoration: none;}
.leftnav a:visited{color:#333333; text-decoration: none;}
.leftnav a:hover{color:#333333; text-decoration: underline;}

Any suggestions?

Thanks

margin: 0 5px; 0 5px;

This line has one too many ;'s.

Are you using a strict doctype? Inconsistencies like this can occur if you're not.
