Below your recordset you would need to add the code to get the recordcount. It is added by DW when you add the record count variable to the page, but you can add it manually it is:

<%
' *** Recordset Stats, Move To Record, and Go To Record: declare stats variables

' set the record count
Recordset1_total = Recordset1.RecordCount

' set the number of rows displayed on this page
If (Recordset1_numRows < 0) Then
Recordset1_numRows = Recordset1_total
Elseif (Recordset1_numRows = 0) Then
Recordset1_numRows = 1
End If

' set the first and last displayed record
Recordset1_first = 1
Recordset1_last = Recordset1_first + Recordset1_numRows - 1

' if we have the correct record count, check the other stats
If (Recordset1_total <> -1) Then
If (Recordset1_first > Recordset1_total) Then Recordset1_first = Recordset1_total
If (Recordset1_last > Recordset1_total) Then Recordset1_last = Recordset1_total
If (Recordset1_numRows > Recordset1_total) Then Recordset1_numRows = Recordset1_total
End If
%>
<%
' *** Recordset Stats: if we don't know the record count, manually count them

If (Recordset1_total = -1) Then

' count the total records by iterating through the recordset
Recordset1_total=0
While (Not Recordset1.EOF)
Recordset1_total = Recordset1_total + 1
Recordset1.MoveNext
Wend

' reset the cursor to the beginning
If (Recordset1.CursorType > 0) Then
Recordset1.MoveFirst
Else
Recordset1.Requery
End If

' set the number of rows displayed on this page
If (Recordset1_numRows < 0 Or Recordset1_numRows > Recordset1_total) Then
Recordset1_numRows = Recordset1_total
End If

' set the first and last displayed record
Recordset1_first = 1
Recordset1_last = Recordset1_first + Recordset1_numRows - 1
If (Recordset1_first > Recordset1_total) Then Recordset1_first = Recordset1_total
If (Recordset1_last > Recordset1_total) Then Recordset1_last = Recordset1_total

End If
%>


Currently it looks like the total isn't set correctly so it is always zero and alway valid.
