ASP Focus problem

I have an input box "DispatchNote", if this is blank I want to set the focus to it, if it is not blank I want to set the focus to SerialNo. I have tried this but it is not working: -
</head>
<% 
if Dnote = "" or isnull(Dnote) then
%>
<body bgcolor="#A1FC03" text="#000000">
<form name="AddSerials" action="Serials.asp" method="post" defaultfocus ="DispatchNote">  
<% 
Else
%>
<body bgcolor="#E5EC09" text="#000000">
<form name="AddSerials" action="Serials.asp" method="post" defaultfocus ="SerialNo">  
<% 
end if
%>

Open in new window

Can anyone help?

the defaultfocus attribute can only be used with .NET, not classic asp. you can use straight up JS to accomplish what you want:

<script type="text/javascript">
     function setFocus( val ){
          if( val == '' ||val == nul )
              document.getElementById('DispatchNote').focus();
          else
              document.getElementById('SerialNo').focus();
     }
</script>
</head>
<body bgcolor="#A1FC03" text="#000000" onload='setFocus()'>
<form name="AddSerials" action="Serials.asp" method="post">  

rest of html down here

this assumes your text fields have IDs labelled DispatchNote and SerialNo
