I am hoping someone can give me some advice here or whether anybody has had a similar issue.
I am trying to upload a participant table into Lime Survey, with a proportion of the tokens having '-' in them. However, I get an error saying there are invalid tokens as tokens should only contain 0-9, a-z, A-Z or _. Is there a way of changing this criteria so that I can also upload the tokens with '-' in them?
