Hi .jeff

Yeah, I think so.  Just to make sure:

if(current_menu) ****** this line checks to see if the value is anything
other than null

{oMenu = document.getElementById(current_menu); ****** if it is, hide
the <div>
 oMenu.style.display = 'none';			****** with the id value
of current_menu
}

oMenu = document.getElementById(menuId);		****** now get
the value passed to the function
if(oMenu.style.display == 'none' && current_menu != menuId) ****** check
to see if display

****** not none for not the same as already open
{oMenu.style.display = 'block'; ****** set display to block
 current_menu = menuId;		  ****** set value of current_menu to
that of menuId
}

Else					****** if current_menu was a
null value, keep it null and return
current_menu = null;
return false;
}
}

Is that right?
