<!-- Web Site: http://www.nordenterprises.com -->
<!-- developed for use with http://home-owners-assoc.com -->
<!-- Note: while overlib works fine with Netscape 4, this function does not work very well, since portions of the "over" div -->
<!--   end up under other fields on the form and cannot be seen.  If you really want to use this with NS4, -->
<!--   you'll need to change the positioning in the overlib() call to make sure the "over" div gets positioned -->
<!--   away from all other form fields -->
