The javascript to "sync" the frames is incorrect.
It currently reads:
<script language="javascript">
parent.frames('LeftFrame').location.href=('Databases.aspx');
parent.frames('MainFrame').location.href=('setDatabase.aspx');
</script>
Because frames is not a function (it is actually an
array implementation), it should be :
<script language="javascript">
parent.frames['LeftFrame'].location.href=('Databases.aspx');
parent.frames['MainFrame'].location.href=('setDatabase.aspx');
</script>
An easy fix.
