here im just validating my input field whether its valid( i mean just checking the status of my i/p field)
i tried using following code but its not working..if anyone has any code to call stored procedure..plz post it

Conn = Server.CreateObject("ADODB.Connection");
Conn.Open ("Provider=MSDAORA;Data source=c_d;uid=abc;pwd=123;");

Comm = Server.CreateObject("ADODB.Command");
comm.ActiveConnection = conn
comm.commandtype=4
comm.commandtext = "cp_pkg.get_Appr"
param = comm.createparameters
comm.parameters.Append(comm.createparameter("p_id" ,200,1))
comm.parameters.Append(comm.createparameter("p_em_ status",200,2))
comm("p_id") = "id"
output = comm("p_em_status")
