I dynamically populate repeating section fields they became labels and are not saved in list. How to save them?

I tried both modes: New and Edit. I do not have any rules. Yes, it is connected to the Multiline. I populated these fields using script. All those fields are from calculated value fields.

Manfred, it does not work. I execute addRowToMySection function on click.

function addRowToMySection() 
  {
   var rs = null;
  NWF$(document).ready(function() {
  rs = NWF$(".MOsRep .nf-repeater-row:last"); 
   var lookUpTaxId = NWF$("#" + CalcTaxId);
  var lookUpTaxIdVal = lookUpTaxId.val();
  var taxId = NWF$(rs).find(" .repMosTaxId");

var fName = NWF$(rs).find(".repMosFirst ");
  var lName = NWF$(rs).find(".repMosLast");
  var rank = NWF$(rs).find(".repMosRank");
  var cmdCode =  NWF$(rs).find(".repMosCmdCode");
  var cmdName = NWF$(rs).find(".repMosCmdName");
  var calcFName= NWF$("#" + Calc_fnm);

 var fVal = calcFName.val();
  var sqlLName= NWF$("#" + Calc_lnm);
  var lVal = sqlLName.val();
  var sqlRank= NWF$("#" + Calc_rank);
  var rankVal = sqlRank.val();
  var sqlCmdCode= NWF$("#" + Calc_cmdCode);
  var CmdCodelVal = sqlCmdCode.val();

var sqlCmdName = NWF$("#" + Calc_cmdName);
  var cmdNameVal = sqlCmdName.val();
  if (lookUpTaxIdVal == "")
{
 alert ( lookUpTaxIdVal + " is not found");
}
else

{

NWF$ (taxId.text(lookUpTaxIdVal) );
 NWF$(fName.text(fVal));
  NWF$(lName.text(lVal));
  NWF$(rank.text( rankVal));
  NWF$(cmdCode.text(CmdCodelVal));
  NWF$(cmdName.text(cmdNameVal));
   NWF.FormFiller.Functions.ProcessOnChange(cmdName);
 }

});
  NWF$(".MOsRep").find('a').click(); 
}

Marian, where should I populate it?

hard to guess how you have structured your form and what elements you address with lot of different classes within your code,  just off top of head I think something like this might work (or at least point you to working direction)

fName.find('.nf-associated-control').val(fVal);‍
