    Hi, Thanks for the article. I tried to use the regular expression [\w]{10,255}, but it is not working. It always throws error. I used this regex in Text type and conditioned it as “contains”. Where am i going wrong?

      Hi. I tried the regex [\w]{10,255} for both question types, “Paragraph text” and “Text” , and it worked well. You could send me the link with a screenshot where the form shows an error, so I can take a look.

    Hello, I wanted to know if there’s a way to make it compulsory for the respondents to answer a particular question if they choose a particular option. e.g. if they choose 3 or less on a 5 digit scale, the next question labelled suggestions becomes compulsory to answer but not at a 4 or 5. Alternatively, the same question may offer an explanatory field on choice of a 3 or less.

      Maybe you can try with conditional branching but I am not sure whether it will address your question completely.

    This expression is just what I needed. I modified it to accept other e-mail formats like .edu and .co.
