<!--
Dim i

strSort = ""

For i = 1 to 3
   ' Determine which dropdown lists contain field names.
   If Document.All.Item("sortList" & i).Value <> "" Then
      ' Add the field names to the sort order sting.
      strSort = strSort & Document.All.Item("sortList" & i).Value 
      If Document.All.Item("OptionDsc" & i).Checked = True Then
         ' Add the word "Desc" (to sort the field in descending order)
         '   and a list separator to the sort string.
         strSort = strSort & " Desc, "
      Else
         ' Add a list separator to the sort string. It will automatically
         '   sort the field in ascending order, however, you could include
         '   then word "Asc".
         strSort = strSort & ", "
      End if
   End if

' Remove the extra characters from the end of the sort string
If Right(strSort, 2) = ", " Then
   strSort=Left(strSort, Len(strSort)-2)
