Thanks so much for all the help so far - my experiment has come together like a dream. I have one last question about input and uppercase letters.
The participants are required to input multi character responses and I'm using the template here https://forum.cogsci.nl/discussion/4737/text-input-form-for-use-with-jatos#latest to save them as a string as independent variables.
However, as the answers may be in German (where they should be capitalised) I thought a work around would be to make all input appear in capitals. Later in the experiment their typed responses are shown to them again and it would look best if they were UPPERCASE.
I've included a screenshot of what I'm working with. Thanks for any pointers you can give :)
