Sorry if this is an obvious one, I'm very new to this. I have everything working as I need it apart from one thing.
When I check 'Upload a video' I want the 'Link to a video online' box to uncheck. I tried the "disableOptions" but this just greys the option out, I need the value to return to "0" so both boxes cant ever be checked at the same time.
Unfortunately, there’s no way of doing this with checkboxes. I would suggest using a list item to choose the video mode, along with sections for the two option fields. That way you can use the Boolean values of the list states as conditions in the code.
