  Dear oriane_g26,

  your script had several mistakes (syntactic and semantic). However, these should have led to Exceptions with detailed error descriptions, rather than not showing TextBoxes. Which Expyriment version are you using, and on which OS?

  In any case, here is a version of your script that runs without producing any errors:

  import expyriment
  
  expyriment.control.set_develop_mode(True)
  
  narratives = [{"beginning": "narrative", "possible_endings": ["ending1", "ending2", "ending3", "ending4"]},
          {"beginning": "narrative", "possible_endings": ["ending1", "ending2", "ending3", "ending4"]},
          {"beginning": "narrative", "possible_endings": ["ending1", "ending2", "ending3", "ending4"]},
          {"beginning": "narrative", "possible_endings": ["ending1", "ending2", "ending3", "ending4"]},
          {"beginning": "narrative", "possible_endings": ["ending1", "ending2", "ending3", "ending4"]},
          {"beginning": "narrative", "possible_endings": ["ending1", "ending2", "ending3", "ending4"]},
          {"beginning": "narrative", "possible_endings": ["ending1", "ending2", "ending3", "ending4"]},
          {"beginning": "narrative", "possible_endings": ["ending1", "ending2", "ending3", "ending4"]},
          {"beginning": "narrative", "possible_endings": ["ending1", "ending2", "ending3", "ending4"]},
          {"beginning": "narrative", "possible_endings": ["ending1", "ending2", "ending3", "ending4"]},
          {"beginning": "narrative", "possible_endings": ["ending1", "ending2", "ending3", "ending4"]},
          {"beginning": "narrative", "possible_endings": ["ending1", "ending2", "ending3", "ending4"]}]
  
  exp = expyriment.design.Experiment(name= "M2PCA Experiment")
  expyriment.control.initialize(exp)
  
  block1 = expyriment.design.Block(name = "stories")
  for counter, narrative in enumerate(narratives):
      trial = expyriment.design.Trial()
      trial.set_factor("Narrative", counter+1)
      stim = expyriment.stimuli.TextBox(narrative["beginning"], (300, 300))
      stim.preload()
      trial.add_stimulus(stim)
      trial.possible_endings = narrative["possible_endings"]
      block1.add_trial(trial)
  block1.shuffle_trials()
  exp.add_block(block1)
  exp.add_bws_factor("Ending", [1, 2, 3, 4])
  exp.add_data_variable_names(["Narrative", "Ending", "RT"])
  
  expyriment.control.start() # This will create a subject ID
  
  for trial in exp.blocks[0].trials:
      ending = exp.get_permuted_bws_factor_condition("Ending")
      trial.set_factor("Ending", ending)
      stim = expyriment.stimuli.TextBox(trial.possible_endings[ending-1], (300, 300))
      trial.add_stimulus(stim)
  
      for stimulus in trial.stimuli:
          stimulus.present()
          key, rt = exp.keyboard.wait(expyriment.misc.constants.K_SPACE)
  
      exp.data.add([trial.get_factor("Narrative"), trial.get_factor("Ending"),rt])
  
  expyriment.control.end()
  

  Hope this helps!

  Thanks for your answer,
  I've tried with your modifications but again there is a black screen with just one grey letter on it

  What you are seeing there is what I saw with parts of your script. Are you sure you are actually using the version I sent you?
