Not quite following what you need, but if you are needing to pull info from your database you would somthing like this:
set rs = Server.CreateObject ("ADODB.Recordset")
Set conn = Server.CreateObject("ADODB.Connection")
Conn.ConnectionString = "Provider=SQLNCLI;Server=SERVER\SQLEXPRESS;Database=Data;Trusted_Connection=yes;"
Conn.Open
sql = "SELECT * FROM [MyData] WHERE [MyData].[CustomerID]=" & Request.QueryString("CustomerID")
rs.open sql, conn, 3, 3
session("check_box")=rs("CheckBox")
rs.Close
Conn.Close
Response.Redirect "/myfolder/myform.asp"
Response.End
<%=session("check_box"))%> <-- Then Put that in initial value of the check box.
