strored procedure

[EyeTalion]

I'm getting this error msg when I run my SP through my app:

ORA-06550: line 1, column 7:
PLS-00201: identifier 'SP_PCMS_APPROVE_CARD' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored


is there something wrong with my code or is the problem in the SP?

thanks

Dim objCommand As New OleDbCommand()
        Try
            objCommand.Connection = objCon
            objCommand.CommandText = "SP_PCMS_APPROVE_CARD"
            objCommand.CommandType = CommandType.StoredProcedure
            objCommand.Parameters.Add(New OleDbParameter("t_card", OleDbType.Numeric)).Value = cardNo
            objCommand.Parameters.Add(New OleDbParameter("t_end_date", OleDbType.Date)).Value = tranPeriodEnd
            objCommand.Parameters.Add(New OleDbParameter("t_error", OleDbType.VarChar, 1)).Direction = ParameterDirection.Output
            objCon.Open()
            objCommand.ExecuteNonQuery()
        Catch ex As Exception
            MsgBox(Err.Description)
            txtbox1.text = Err.Description
        Finally
            objCon.Close()
            recstatus = objCommand.Parameters(2).Value
        End Try
