Advance only to the next item when a selection has been made

  Hi Felix,

  You will need a bit of Python inline code to do this. The logic is explained in this post (my first comment in this discussion):

  Because the solution provided here was written for an older version of OpenSesame, I uploaded a new working example here:

  (Save with the extension .osexp and run as normally.

  I hope this helps.

  Best wishes,

  Hi Felix,

  The part of code you'll need is the following. It should be put in the Prepare phase tab of an inline_script item that is placed after the form_multiple_choice item(s):

  while True:
      # Prepare and run the multiple choice forms (you'll have to adapt the names to your own experiment):
      items.prepare("form_multiple_choice")
      items.run("form_multiple_choice")
  
      # If no response is given, continue to show the form.
      # Otherwise, break from this while loop and advance to the next item
      if var.response != "no":
          break
  

  I attached an example experiment.

  Good luck and let us know if you have any further questions!

  Hey Lotje,

  Thank for sharing your solution. I am fairly new to OP as well and have a similiar problem as Felix has/had.

  I tried out your script and it works great for form_multiple_choice, although I had to place it in the Run phase of the inline script because when I run the experiment and your code was placed in the Prepare phase, it skipped the forms before the first form_multiple_choice and started with the first form_multiple_choice. When placed in the Run phase, it works fine though.

  My actual questions is something diffrent...

  I tried to apply this script to form_base. I have a couple of them in my experiment and most of them include one or two rating scales and a "next" button to advance to the next form. The script works when pressing the button the first time but advances anyway when pressing the button a second time. Do have any idea how to fix this? Many thanks already!!!!

  Best,
  David

  Sorry, I have to correct myself!

  When placed in the Run phase, two responses have to be given no matter what. So even if I respond correctly, I have to do it twice.

  Hi David,

  Would you mind sharing your experiment? Then, I could have a look.

  Besides, the newest version of Opensesame (3.2.1), has a new feature that is called form validation. With that you don't need to have this extra inline_script, but you can simply set what type of responses are required to proceed with the next item. If you upgrade, your life will probably be a little easier.
