Valter,
OK, go back to your previous code but remove the if statement that evluates the
recordcount. Run it and let me know how it goes.

The code I did attach to my previous email was running but the page wasnt
displaying anything (blank). I did try to copy and run your code and it returns
me an error:
Object doesn't support this property or method: 'ObjRS.Field'
Ciao

Valter,
What happens when you run the code?
The only thing that jumps out at me is the line that checks the recordcount. I
put this in to ensure that you get 2 records back. But you may want to remove
it and try it to see if you get different results.
Also, try to reduce the opening & closing asp tags. It makes it easier to read:
<%@ LANGUAGE ="VBSCRIPT" %>
<%
Dim ChartDB
Dim ChartDBPath
strChartDBPath = Server.MapPath("pippo.mdb")
set ChartDB = Server.CreateObject("ADODB.Connection")
ChartDB.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strChartDBPath &
";"
set ObjRS = Server.CreateObject("ADODB.RecordSet")
ObjRS.Open "select TOP 2 id_value, value from valori order by id_value desc",
ChartDB, 2, 3
Do While Not ObjRS.EOF
strValue1 = ObjRS.Field("value")
strValue2 = ObjRS.Field("value")
If strValue2 = strValue1 then
%>
<tr>
<td><img src="../magazine/uptrend.gif"></td>
</tr>
<%
end if
ObjRS.MoveNext
Loop
ObjRS.Close
set ObjRS = Nothing
ChartDB.Close
set ChartDB = Nothing
%>

Thank you so much for your help,
I did follow your advice but yet (sure its my fault) I couldnt get through it.
I attach my code lines (this is just a trial version) so that you will easily
find out where i do mistake.
Thank you again for your kindness.

This should get the last 2 records in your table:
select top 2 id_value, [date], value
from tblTest
order by id_value desc
The following assumes that you have the code to get your data and shows how you
can get the values and subract them in order to get your difference:
If ObjRS.RecordCount = 2 Then
'We have our 2 records. Get the value into var's
strID1 = ObjRS.Fields("id_value")
strDate1 = ObjRS.Fields("date")
strValue1 = ObjRS.Fields("value")
'Move to the second record.
strID2 = ObjRS.Fields("id_value")
strDate2 = ObjRS.Fields("date")
strValue2 = ObjRS.Fields("value")
'Destroy our recordset object.
set ObjRS = Nothing
'Get the diff between our 2 values.
Dim strDifference
strDifference = strValue2 - strValue1
'Display all your data!
End If

The Access db table (QUOTATIONS) has the following fields:
id_value date value
1 12/04 4.85
2 13/04 4.87
3 14/04 4.83
id_value is a "Counter" field
date is a "text" field
value is a "Numeric" field
The page layout should look like this:
previous value last value variation
4.87 4.83 (last value - previous
value) -0.04
So I need to know how to get the last 2 records of my table.
Actually I do not have a code to show coz all is based on this....
Thank you for your help,
