does not work in IE

i'm getting error on page warnings come up for internet explorer and the timeline wont display on the page - i get the outline of it and the instructions at the bottom but that's it! it says unexpected character occured on line 164 character 48 - this is line 164, i can't work out whats going wrong:

        <!-- begin content --><div class='view view-npe-timeline-nodes'><div class='view-content view-content-npe-timeline-nodes'><div class="timeline-wrapper"><div id="npe_timeline_nodes" class="timeline" style="width: 100%; height: 400px"></div></div><div class="timeline-controls" id="npe_timeline_nodes-controls"></div><script type="text/javascript">if (isJsEnabled()) { addLoadEvent(function() { var timeline = createTimelineWidget("npe_timeline_nodes", Timeline.HORIZONTAL, "Wed Mar 14 2007 21:53:04 GMT+0000", 0, [ Timeline.DateTime.DAY, Timeline.DateTime.MONTH ], "/timeline/json?view=npe_timeline_nodes", "json"); setupTimelineControls($('npe_timeline_nodes-controls'), timeline, "Filter:", "Highlight:", "Clear All"); }); }</script></div><div class='view-footer view-footer-npe-timeline-nodes'><p>Drag timeline forward or backward to see more content.</p>

it diplays brilliant in firefox but unfortunately people still use IE even though it is rubbish... :D
