calling an oracle stored proc in an asp page

calling a stored procedure from an ASP page through ADO. my background is in SQL, so pardon my oracle-ignorance. below is a sample of the asp we're attempting, I'm getting an error on the j.execute line, saying it's either a syntax or access violation. I'm unsure if oracle needs rights granted to the stored procedures or if I'm just using the wrong syntax.

Thanks for any help you can provide!

asp code below:

Dim j, c, r'*********************************************stored procedure section begins
Set c = Server.CreateObject("ADODB.Connection")
c.ConnectionTimeout = Application("Scheduler_ConnectionTimeout") 'looking for Scheduler
c.CommandTimeout = Application("Scheduler_CommandTimeout")
c.Open Application("Scheduler_ConnectionString")
Set j = Server.CreateObject ("ADODB.Command")
Set r = Server.CreateObject ("ADODB.Recordset")
Set r.ActiveConnection = c
Set j.ActiveConnection = c

j.CommandType = adCmdStoredProc
j.CommandText = "bbq"
' Add the Return Value Parameter
j.Parameters.Append j.CreateParameter("return", adInteger, adParamReturnValue )

'Add the Input Values
j.Parameters.Append j.CreateParameter("res_id", adInteger, adParamInput )
j.Parameters.Append j.CreateParameter("start", adDBTimeStamp, adParamInput )
j.Parameters.Append j.CreateParameter("end", adDBTimeStamp, adParamInput )
j.Parameters.Append j.CreateParameter("off", adInteger, adParamInput )


'Add the output parameter
j.Parameters.Append j.CreateParameter("start1", adDBTimeStamp, adParamOutput )
j.Parameters.Append j.CreateParameter("end1", adDBTimeStamp, adParamOutput )
j.Parameters.Append j.CreateParameter("result", adInteger, adParamOutput )

'Add Values to Input Params
j("res_id") = resource_id 'sets resource id value for the stored procedure
j("start") = date_desired.value&" "&start_time_desired 'sets start time value for the stored procedure
'j("end") = OracleDateTime(date_desired.value&" "&end_time_desired) 'sets end time value for the stored procedure
j("end") = date_desired.value&" "&end_time_desired
j("off") = offsetion 'sets offset value for the stored procedure
j("start1") = null 'this null value is for a output parameter from the stored procedure
j("end1") = null 'this null value is for a output parameter from the stored procedure
j("result") = NULL 'this null value is for a output parameter from the stored procedure
j.Execute
