I am trying to test this script. I am unable to get past the2nd line

• VariableDispenser.LockForRead(“User::filename”);.

I get the error

• System.Runtime.InteropServices.COMException: ‘The variable cannot be found.

  public override void CreateNewOutputRows()
  {
  IDTSVariables100 vars = null;
  VariableDispenser.LockForRead(“User::filename”);
  VariableDispenser.LockForRead(“User::cycle”);
  VariableDispenser.LockForRead(“User::inputfileid”);

  VariableDispenser.GetVariables(out vars);

  string InputFile = vars[“User::filename”].Value.ToString();
  string Cycle = vars[“User::cycle”].Value.ToString();
  int InputFileID = (int)vars[“User::inputfileid”].Value;
  vars.Unlock();

  // Create the StreamReader object to read the input file
  System.IO.StreamReader reader =
  new System.IO.StreamReader(Path.Combine(InputFile,Cycle,”details.txt”));

  // Loop through the file to read each line
  while (!reader.EndOfStream)
  {
  // Read one line
  string line = reader.ReadLine();
