Javascript, ist Null oder kein Objekt

[Sunny C.]

Hallo zusammen,

auf meiner Seite verwende ich folgendes "javascript- Tooltip"
Im Firefox (wie immer) geht alles reibungslos! Doch im IE 7 und IE Tab von Firefox gehen die ToolTips nicht, folgendes bekommt man zu Gesicht:



Zeile 155 wäre in der JS Datei:

Code: [Select]

toolTipSTYLE.top  = y + offsetY;
Ein Link wird so gesetzt:

Code: [Select]

<a href="#" onmouseover="toolTip('Du kannst 3 Fotos deiner Wahl und ein Video von dir hochladen!');" onmouseout="toolTip();" target="_blank" border="0">Fotos hochladen</a>
Dieser Code muss in der Datei vorhanden sein:

Code: [Select]

<!--
<div id="toolTipLayer" style="position: absolute; visibility: visible; display: none; left: 228px; top: 54px; width: 163px; height: 50px">
  <table bgcolor="#000000" border="0" cellpadding="0" cellspacing="1" width="160">
    <tbody>
      <tr>
        <td><table bgcolor="#ffffcc" border="0" cellpadding="5" cellspacing="0" height="100" width="160">
            <tbody>
              <tr>
                <td align="left">&nbsp;</td>
              </tr>
            </tbody>
          </table></td>
      </tr>
    </tbody>
  </table>
</div>
//-->
<b><font face="Arial, Verdana, Helvetica, sans-serif" size="1">
<script language="JavaScript" type="text/javascript">
<!--
initToolTips();
//-->
</script>
Das ist die JS Datei:

Code: [Select]

var ns4 = document.layers;
var ns6 = document.getElementById && !document.all;

}

{

}
