widget position

Lovely widget! I’ve installed it on http://digitaldevotee.com but seem not to be able to control the position though the css for that widget area says float: right which is what i want (below). any suggestions?

#sidebar-header {
overflow: hidden;
float: right;
width: 49.78723404255319%; /* 468 / 940 = 0.4978723404255319 */
height: 60px;
margin-bottom: 20px;
}
