Session Variable in a Command Object

Hi all,
How would I insert a session variable in place of Request.Form variable in the following code:

<%

Set Command1 = Server.CreateObject ("ADODB.Command")
Command1.ActiveConnection = MM_skilledovertime_STRING
Command1.CommandText = "DELETE FROM Employeedata WHERE last5=?"
Command1.Parameters.Append Command1.CreateParameter("MMColparam", 200, 1, 9, MM_IIF(request.form("last5"), request.form("last5"), Command1__MMColparam & ""))
Command1.CommandType = 1
Command1.CommandTimeout = 0
Command1.Prepared = true
Command1.Execute()

%>
Instead of "(request.form("last5"), "
it would be a (session("last5")

Thanks,
Lenny
