John,

I think you need to take the date strings, convert them to dates, and then use the dates variables. So, first get the date variables:

   dim dRdate1   as DateTime = DateTime.Parse(Request.Item("d1"))
   dim dRdate2   as DateTime = DateTime.Parse(Request.Item("d2"))

Then use the date variables in your string:

dim MySql as string=String.Format("select sdate1,sdate2,Title from Sess " + _
"where id_code={0} and between(sdate1,{1},{2}), Request.Item("ID"), dRdate1, dRdate2)
