var flag;
var flg;

function addRecipient()
{

 var indxrecp=document.getElementById('cmbRecp').selectedIndex;
 var recpId=document.getElementById('cmbRecp').options[indxrecp].value
 var recpnam=document.getElementById('cmbRecp').options[indxrecp].text

 var l=document.getElementById("cmbselRecp").options.length
 var flg=0


if(indxrecp >= 0)
{
 // Create an Option object        

        var opt = document.createElement("option");
        opt.text =  recpnam;
        opt.value = recpId;

// Add an Option object to Drop Down/List Box

 for(flg=0,i=0;i<l;i++)
 {

   if(document.getElementById("cmbselRecp").options[i].value==recpId)
   {
    flg=1
    break;
   }
 }

 {
  document.getElementById("cmbselRecp").options.add(opt);
  //document.getElementById("txtselrecp").value=
