It is an internal site. Here is an example of the code.
Create two files (top.htm, test.htm) both in same location. Copy the source into the file.
top.htm
<input type="button" value="clickme" onclick="document.testFrame.location='test.htm#here';" />
<table>
<tr valign="top">
<td><div style="height: 1800px;"></div></td>
<td><iframe name="testFrame" width="300" height="300" src="test.htm"></iframe>
</td>
</tr>
</table>
test.htm
<div style="height: 800px;"></div>
<a name="here"></a>
Thanks for all the help,
