Code looks something like (connection is defined above):

ps_SQL="exec StoreProcedure"&_
"@InputParam = ? ," &_
"@OutputParam = ? output"

Set Cmd1 = Server.CreateObject("ADODB.Command")
Cmd1.ActiveConnection = Conn
Cmd1.CommandText = ps_SQL
Set Param1 = Cmd1.CreateParameter(,3,1)
Param1.value= someValue
Cmd1.Parameters.Append Param1
Set Param1 = Nothing

Set Param2 = Cmd1.CreateParameter(,3,2)
Cmd1.Parameters.Append Param2
Set Param2 = Nothing

Set Rs = Cmd1.Execute()
Response.Write "Cmd1.Parameters(0).Value=" & Cmd1.Parameters(0).Value
Response.Write "Cmd1.Parameters(1).Value=" & Cmd1.Parameters(1).Value
Response.End

Output for Parameters(0) is as expected though for Parameters(1) output is blank.
StoreProcedure returns what is expected, when run from analyzer.

What is wrong in the code?
Or maybe somebody can point me to the code that works?
Thanks in advance.
