Several click boxes on screen but only one failure caption appearing

Hi,

I'm using Captivate 6 and I have 3 click boxes on one slide. I have set each click box to have a Failure caption however, only the failure caption of the click box in the top position of the timeline appears in the course.

Ideally I want all 3 captions to appear at once if the user fails to click in any of the correct areas.

Do anyone know how to fix this?

Thanks in advance.

Liam
