  To Hulya:

  RE your first question, I would manually add <br> to break your long text into multiple lines and present it in sketchpad. A pain I know. But you can automate this process in any programming languages.

  
  

  To OS community:

  I have the same question 2. I would like to counterbalance participants across four lists. I typically do this using subject_nr in the desktop programme. In OSWeb, if I enter '1-4' in 'possible subject numbers', OSWeb seems to randomly assign one of the subject numbers to a new participant. I wonder whether the allocation of possible subject numbers is automatically counterbalanced or whether it is just random (meaning the number of participants on each subject_nr will be roughly equal if the sample is big enough but unlikely to be matched exactly.)?

  If it is the latter, i.e. counterbalancing is not built in in OSWeb, any suggestions on how to implement this?

  Many thanks!

  Hi boyao!

  Thank you for your answer for the first question. I keep forgetting that I may need workarounds with HTML tags! Thanks a lot, it worked wonders.

  My second question remains, and thanks for detailing it as well :)

  Best,

  Hülya

  Hi Hulya,

  counterbalancing across participants can be done with inline_javascript. In python the code is:

  if var.subject_nr<12:
      var.condition = 1
  else:
     var.condition= 2 
  

  (of course you need to adapt the precise conditions to your needs.

  Also as mentioned, this is Python code, so you would have to translate it to javascript to make it osweb compatible. For this simple code, it shouldn't be too complicated though. See here: https://osdoc.cogsci.nl/3.2/manual/osweb/#inline-javascript
