How can I conditionally show a field based on user input?

I have another query for the same file.
Under question “ I will be available from” there is the option “other”. If this is ticked, then I’d like a text box to open up. How can I do this?

Hi again 😊 I just noticed that you already asked this same question twice on different threads:

We kindly implore you to stick with 1 topic per thread and avoid posting multiple threads about the same question.

I checked both of the threads above and it looks like my colleague have given ample instructions on this thread.

So, if you have something to add or have a followup question, please don't reply via email. Instead, open your previous thread by clicking this link, then post your reply from there.
