In my form, I have a text question. I would like to prevent users from responding to this question witlh multiline responses. What is the constraint that i should use? From the documentation, there is this function:
contains(string, substring)
It was not my intention to accept multiple responses using this question but somehow the users discovered that they can input multiple responses by pressing the enter key and then typing in the next response. So I have instances where in this text question, there are 5 rows of responses, made possible by creating a new line using the Enter
key.
I would like to know how to detect multiple rows using the contains
function.
Thanks
