Responses to the questionnaire I created should be between 1000 and 1800 characters, or between 200 and 300 words. I don't know which regular expression / option to use so that my participants can see how many characters they have already used. I found this regular expression :
strlen(self.NAOK)
The problem is that I already have a regular expression in Logic --> question validation equation:
strlen(self) > 1000 (to set the minimum number of characters to 1000).
The consequence is that I don't know where to put this new regular expression, and I don't know if it works. What do you think I should do ?
