<div id='KB1Parent' class='parent'><a href="default.htm" onClick="expandIt('KB1'); return false">
<IMG SRC='plus.gif' BORDER=0>MAIN</a></div><div id='KB1Child' class='parent'>

When you click on the "MAIN", the menu will expand, you click again the menu will fold, however when i tried to link a page to "MAIN" the link does not work, how to do?
