Security Assist "Please enter a value" error
Hello,
I have just used SecurityAssist to make its family of pages.
The login page keeps giving me the above error, and I am not sure why. 
"Please enter a value".
The entries in the database being checked against were manually pre-entered, in case that makes a difference.
And in case it helps, here is the code generated in what I think is the appropriate part:
I will p;ut the URL to the relevant page in the private area.
Thank you.
<?php 
 if ((isset($_POST["LogIn_submit"]) || isset($_POST["LogIn_submit_x"])))  {
   $WAFV_Redirect = "".($_SERVER["REQUEST_URI"])  ."?invalid=true";
   $_SESSION['WAVT_participantslogin_Errors'] = "";
   if ($WAFV_Redirect == "")  {
     $WAFV_Redirect = $_SERVER["PHP_SELF"];
   }
   $WAFV_Errors = "";
   $WAFV_Errors .= WAValidateRQ((isset($_POST["Log_In_group_UserName"])?$_POST["Log_In_group_UserName"]:"") . "",true,1);
  $WAFV_Errors .= WAValidateRQ((isset($_POST["Log_In_group_2_Password"])?$_POST["Log_In_group_2_Password"]:"") . "",true,2);
  $WAFV_Errors .= WAValidateEL((isset($_POST["Log_In_group_2_Password"])?$_POST["Log_In_group_2_Password"]:"") . "",6,500,true,3);
   if ($WAFV_Errors != "")  {
     PostResult($WAFV_Redirect,$WAFV_Errors,"participantslogin");
   }
 }
 ?>
