There is most likely an error in your JavaScript code. Where does it say 'object expected'? On the actual page or when you double-click the icon in the status bar of Internet Explorer. If it's the latter of the two, then you have a problem in your JavaScript.

				msVATCodeCombo += '<option value="S"<%If sDefaultVATCode = "S" Then Response.Write(" selected")%>>S</option>';
				msVATCodeCombo += '<option value="E"<%If sDefaultVATCode = "E" Then Response.Write(" selected")%>>E</option>';
				msVATCodeCombo += '<option value="Z"<%If sDefaultVATCode = "Z" Then Response.Write(" selected")%>>Z</option>';
				msVATCodeCombo += '<option value="L"<%If sDefaultVATCode = "L" Then Response.Write(" selected")%>>L</option>';
				msVATCodeCombo += '<option value="A"<%If sDefaultVATCode = "A" Then Response.Write(" selected")%>>A</option>';
				msVATCodeCombo += '<option value="AA"<%If sDefaultVATCode = "AA" Then Response.Write(" selected")%>>AA</option>';
				msVATCodeCombo += '<option value="AB"<%If sDefaultVATCode = "AB" Then Response.Write(" selected")%>>AB</option>';
				msVATCodeCombo += '<option value="AC"<%If sDefaultVATCode = "AC" Then Response.Write(" selected")%>>AC</option>';
				msVATCodeCombo += '<option value="B"<%If sDefaultVATCode = "B" Then Response.Write(" selected")%>>B</option>';
				msVATCodeCombo += '<option value="C"<%If sDefaultVATCode = "C" Then Response.Write(" selected")%>>C</option>';
				msVATCodeCombo += '<option value="G"<%If sDefaultVATCode = "G" Then Response.Write(" selected")%>>G</option>';
				msVATCodeCombo += '<option value="H"<%If sDefaultVATCode = "H" Then Response.Write(" selected")%>>H</option>';

Using ASP, it is possible to write JavaScript to the page, but not actually call it. Are you sure the function is available to the page? Are you including it or copying and pasting it to each page?

I'm trying to reproduce your error, but it says 'msVATCodeCombo' is undefined. How are you defining this so I may test?

hi
Code:
	<script type="text/javascript">
		var mbSubmitting = false;
		var msUOMDropdown = '';
		var msVATCodeCombo = '';
declared as global varaible.

Guddu,

Here's a test I ran that worked using your function:

Code:
<html>
    <head>
        <% Dim sDefaultVATCode, lCount
           sDefaultVATCode = "S"
           lCount = 3
        %>
        <script language="javascript" type="text/javascript">
        <!--
        var msVATCodeCombo = '';
        function dd()
 {
     if(msVATCodeCombo == '')
   {
       msVATCodeCombo += '<option value="S"<%If sDefaultVATCode = "S" Then Response.Write(" selected")%>>S</option>';
       msVATCodeCombo += '<option value="E"<%If sDefaultVATCode = "E" Then Response.Write(" selected")%>>E</option>';
       msVATCodeCombo += '<option value="Z"<%If sDefaultVATCode = "Z" Then Response.Write(" selected")%>>Z</option>';
       msVATCodeCombo += '<option value="L"<%If sDefaultVATCode = "L" Then Response.Write(" selected")%>>L</option>';
       msVATCodeCombo += '<option value="A"<%If sDefaultVATCode = "A" Then Response.Write(" selected")%>>A</option>';
       msVATCodeCombo += '<option value="AA"<%If sDefaultVATCode = "AA" Then Response.Write(" selected")%>>AA</option>';
       msVATCodeCombo += '<option value="AB"<%If sDefaultVATCode = "AB" Then Response.Write(" selected")%>>AB</option>';
       msVATCodeCombo += '<option value="AC"<%If sDefaultVATCode = "AC" Then Response.Write(" selected")%>>AC</option>';
       msVATCodeCombo += '<option value="B"<%If sDefaultVATCode = "B" Then Response.Write(" selected")%>>B</option>';
       msVATCodeCombo += '<option value="C"<%If sDefaultVATCode = "C" Then Response.Write(" selected")%>>C</option>';
       msVATCodeCombo += '<option value="G"<%If sDefaultVATCode = "G" Then Response.Write(" selected")%>>G</option>';
       msVATCodeCombo += '<option value="H"<%If sDefaultVATCode = "H" Then Response.Write(" selected")%>>H</option>';
       msVATCodeCombo += '<option value="O"<%If sDefaultVATCode = "O" Then Response.Write(" selected")%>>O</option>';
       msVATCodeCombo += '</select>';
   }
 document.write(msVATCodeCombo);
        }
        //-->
        </script>
    </head>
    <body>
        <%
            Response.Write "<select id=""cboVATCode" & lCount & """ name=""cboVATCode" & lCount & """><script language=""javascript"" type=""text/javascript"">dd();</script>"
        %>
    </body>
</html>
I had to simulate some of your variables (e.g. lCount and sDefaultVATCode) and I had to add this line to your function:

Code:
document.write(msVATCodeCombo);
