Below Code works great but counter still shows 1 even there is no empty filled

Below is the code to get the empty filleds (counter);

form1.Page1.notification.NumericField1::ready:layout - (FormCalc, client)

var FilledRows = 0

for i = 0 upto Body.Table1.Row1.instanceManager.count - 1 do

     if (Body.Table1.Row1[i].drp_names eq null) then

          FilledRows = FilledRows + 1;

          this.rawValue = FilledRows;

     endif

endfor

the code in Javascript to check if the value of the counter is zero

form1.Page1.save_as::click - (JavaScript, client)

   if (notification.NumericField1.rawValue == 0){

  xfa.host.messageBox("This will save your form as PDF form, means you can edit later once more","Save As Form",3,0);

  app.execMenuItem("SaveAs");}

else

{xfa.host.messageBox("You have : " + notification.NumericField1.rawValue + " empty highlighted fields","Empty Fields",3,0);}
