ASP Move File Problem

Hi All,
 
I am trying to move a file using the following code in my asp page. The error I am getting in IE when I run the sub is "object expected" . The path to the following files is on the server and I have full accessrights to the sever. I can't see where am I going wrong? (PS: New to Programming)
 
Many Thanks!

Sub smove()
Dim ID, strInput, strOutput, filesys
ID = "09-123-4"
ID = ID&".txt"
strInput = "d:\tmpdir\"&ID
strOutput = "d:\results\"&ID
Set filesys = CreateObject("Scripting.FileSystemObject")
filesys.MoveFile strInput,strOutput
Set filesys = Nothing
End Sub
%>
<form>
<input type="button" name="move" value="MoveFile" onclick=smove()>
</form>
