Design/UX question.

A form has 3 number inputs. Their values must add up to 100. If they don't, which should be flagged as invalid - the last one touched or all 3?

Or is there a better design?

@chris22smith Perhaps they go in a fieldset, then the error is associated with the fieldset itself rather than any individual input. (Just guessing, here.)
@marcamos That sounds sensible to me, thanks. I've started wondering about an apportionment component but it feels like overkill.
