i think line 14:
$WAFV_Errors .= WAValidateUnique("nrcahub",$nrcahub,$database_nrcahub,"Requesters","RequesterID","int","".((isset($_SESSION["RequesterID"]))?$_SESSION["RequesterID"]:"0") ."","RequesterID","int","((isset($_POST[\"formEmail\"]))?$_POST[\"formEmail\"]:\"\")",true,1);
should be:
$WAFV_Errors .= WAValidateUnique("nrcahub",$nrcahub,$database_nrcahub,"Requesters","RequesterID","int","".((isset($_SESSION["RequesterID"]))?$_SESSION["RequesterID"]:"0") ."","RequesterID","int","".((isset($_POST["formEmail"]))?$_POST["formEmail"]:"")."",true,1);
