'Nige is right with his SQL string examples, but the error you are getting is because you are trying to perform operations on a recordset which has been closed. If you look at your code you will probably find a line such as dbConn.close, or RS.close or Set RS = nothing somewhere before line 473.

That is on the first page you do: 
SELECT * from Table WHERE OrderValue BETWEEN 1 and 10 
Then you pass along the last value to the next page ""show_rewults?start=11"" for example and go from there 
SELECT * from Table WHERE OrderValue BETWEEN 11 and 20
