Google Map - Markers not centering when links are clicked

I’v got a small issue with my google map. All is working ok apart from when I clicked on the links for any of the markers in the sidebar html which was created. The markers are showing up fine and have loaded from the xml file, however, the marker point doesn’t center on the map when I click the link,

Based on the code below, could someone advise how I can get the points/markers to center on the map.

Thanks for any help.

	     <table border=0 cellspacing=10>
      <tr>
        <td>
           <div id="map" style="width: 550px; height: 650px"></div>
        </td>
        <td bgcolor = "lightblue" width = "150px" valign="top" style="text-decoration: none; color: #4444ff;">
           <div id="side_bar"></div>
        </td>

      </tr>

    </table>
