     itemSELECT.setAttribute("name", "item"+rowCount);
     itemSELECT.setAttribute("id", "itemTextId"+rowCount);
     itemOPTION1 = document.createElement(¨option¨);
     itemOPTION1.setAttribute(¨id¨,¨opt1¨);
     itemOPTION1.setAttribute(¨value¨,¨blah¨);
     itemOPTION1.appendChild(document.createTextNode(¨blah¨);
     itemSELECT.appendChild(itemOPTION1);
}

itemTD.appendChild(itemSELECT);

try this

<head>
<script>
function addRow(aTable) {
len=aTable.rows.length
aRow = aTable.insertRow(len);
c1=aRow.insertCell(0)
c1.innerHTML='<select maxlength=3 name="item"'+len+'><option>USA</option><option>CANADA</option></select>'
}
</script>
</head>

<body>
<table id="myTable" name="myTable" border="1">
  <tbody id="myTableTBody" name="myTableTBody">
  </tbody>
</table>
<input type=button id="addRow" value='add row' onClick="addRow(document.getElementById('myTableTBody'))">

</body>
</html>

a non-DOM way:

assuming obj is the select to be fiiled with options:

obj.options[obj.options.length] = new Option("myDescription", "myValue");

the Option constructor has 2 additional optional args to determine if the appended option is selected or not, just see:

Hi srima,

  Why didn't you ask piglet to help you modify the script?  I'm positive he would have been more than happy to :D
