case sensitivity. the line that sets the total rows variable is:
$totalRows_girls_players = mysql_num_rows($girls_players);
you need to use the same case in the server validations.
change:
$WAFV_Errors .= WAValidateNM($totalrows_girls_players . "",-1,0,"",",.",false,1);
to:
$WAFV_Errors .= WAValidateNM($totalRows_girls_players . "",-1,0,"",",.",false,1);
