  Hi @choql ,

  
  

  Have you considered using a form_text_input item instead of a sketchpad - keyboard_response combination?

  When Sebastiaan wrote the student-number example, theform plugins were not yet supported by OSWeb, but now they are (with the exception of the form_base item).

  Hope this helps!

  
  

  Cheers,

  Thank you for your response! However, does 'form_text_input' have a 'correct' or 'response time' variable?

  Again, thank you for your help!

  Hi,

  As far as I know, the forms don't have a correct variable defined. But that isn't terribly difficult to calculate yourself. If you have variable that keeps track of what the correct_response should be, you can simply add these few lines to an inline_script that you put after the form in the sequence (in the run phase!):

  # where response is the variable that you specified in your form the input 
  # should be stored into 
  if var.response == correct_response:
      var.correct = 1
  else:
      var.correct = 0
  

  
  

  response times

  Yes, they should be stored in form_response_time. However, they don't represent when things happen within the form, but only when the form was completed (ok button pressed or whatever), so I don't think there is a straightforward way to extract the time participants needed to make the first key stroke, I am afraid.

  I hope this helps. Let me know if more things are unclear.
