Trigger action if Animation Complete

Hi, I am trying to set up a shape A to come up once animation (motion) for shape B is completed when user click on shape C. It is important for me that the shapes A comes after the animation is completed and not just when I click the shape C.  My triggers are the following:

Change state of Shape A to Hidden when timeline starts

Change state of Shape A to Normal user clicks on shape C when animation completes (Object B, motion path selected).

AWhat am I missing with animation conditions?

Thank you in advance!
