The only way to add the onlaod event is to detach the page form the temlate unfortunately.
the onLoad code has some spaces in it that are causing javascript errors:
<body <? if (isset($_GET['ID'])) { ?> onload="WA_setSelectionsInChildList(MM_findObj('or gID'),<?php echo $row_project['agency']; ?>)" <? } ?> <? if (isset($_GET['ID'])) { ?>onload="WA_FilterAndPopulateSubList(contacts_WAJ A,MM_findObj('orgID'),MM_findObj('contact'),1,0,fa lse,': ')" onload="WA_setSelectionsInChildList(MM_findObj('co ntact'),<?php echo $row_project['contact']; ?>)" <? } ?> >
needs to be changed to:
<body <? if (isset($_GET['ID'])) { ?> onload="WA_setSelectionsInChildList(MM_findObj('orgID'),<?php echo $row_project['agency']; ?>)" <? } ?> <? if (isset($_GET['ID'])) { ?>onload="WA_FilterAndPopulateSubList(contacts_WAJA,MM_findObj('orgID'),MM_findObj('contact'),1,0,fa lse,': ')" onload="WA_setSelectionsInChildList(MM_findObj('contact'),<?php echo $row_project['contact']; ?>)" <? } ?> >
