ORA-01036: illegal variable name/number error

I am getting a "ORA-01036: illegal variable name/number" error when executing my select statement.  All my research indicates that the error is due to a missing parameter.  This query only has one input parameter and one output parameter.  I added checks to the error message to display the value of the paramter and it shows a valid value.

For this testing, the table is empty so it shouldn't return anything.  However, I am not expecting an exception to be thrown.  Does this mean if the record is not found, the ORA-01036 error will be returned?  Is there a way to trap that error so I can display the message, "Division not found."?

        public Int32 FindDivisionByName(OracleConnection connectionObj, String division)
        {
            // Looks for the specified division name in the Division Table and returns the DivisionID if found and the ActiveStatusFlag is Y
            // Otherwise, returns 0;

            Int32 retVal = 0;
            ErrMsg = "";

            // Check that the database has been opened
            if (connectionObj == null || connectionObj.State != ConnectionState.Open)
            {
                ErrMsg = "<br />Database is not opened.";
                return 0;
            }

            // Create Command object
            OracleCommand command = connectionObj.CreateCommand();
            command.Connection = connectionObj;

            try
            {
                // Insert Division information and return DivisionID
                command.CommandText =
                    "SELECT DivisionID FROM EMP_OWNER.EMP_DIVISION " +
                    "WHERE Division = :Division AND ActiveStatusFlag = 'Y'";

                // Remove any previously set Parameters
                command.Parameters.Clear();
                command.Parameters.Add("Division", OracleDbType.Varchar2, 30, ParameterDirection.Input).Value = division;
                command.Parameters.Add("retPK", OracleDbType.Int32, ParameterDirection.Output);
                retVal = (Int32)command.ExecuteScalar();
            }
            catch (Exception ex)
            {
                ErrMsg = "ERROR Searching Division Data: " + ex.Message + "<br />Division =" + division + "<br />Parameter: " + command.Parameters["Division"].Value;
                retVal = 0;
            }
            finally
            {
                command.Dispose();
            }

            return retVal;
        }

Comment out the following line and try it again:
command.Parameters.Add("retPK", OracleDbType.Int32, ParameterDirection.Output);

Hmm is it just me or you are not referencing/setting the output parameter at all in your commandtext?

I had copied the code from an Insert Statement and modified it for my select and never removed the output parameter.  Can't tell you how long I stared at the code without seeing it.  Thanks.
