Hi!
I am working on a survey wherein the form will automatically tick a value in the select multiple question if he/she has an answer in a certain question.
For specifics, if the user has an input in the Shopping Amount, that will automatically select Shopping as other activity in a select_multiple question.


Client also wants that the Shopping Amount be required if user has selected Shopping in either one of the two questions above - that one I figured that out, but the other requirement is still unsolved.
Is there any way to do this? Any help would be appreciated. Thank you in advance.
