I have a question about using using concat for creating a string based on previous answers in the same survey. I'm using the concat function to create a custom url to prepopulate answers for next steps in my survey. This works ok for the most question types, however when I use concat for select_one or select_multiple types the result is converted into ["result"]. Does anyone know how to solve this to get for example A,B,C instead of ["A,B,C"]?
I've found a trick by first creating an extra note field with the result of my select_multiple, and afterwards using this new note field in my concat function to create a string. I have however a lot of select_multiple fields and was hoping there is a better way than creating a lot of extra note fields. In the provided calculations sample this also occurs.
