If you want to trigger something after the animation has completed, select the Fadein animation and override its onAnimationFinished, get the Boarder->SetVisibility:Hidden
You need to Select the Fadein animation, go to the details panel and hit the green + button. This will create an Event with the correct signature for the animation. It will have the animation name in brackets, like in my image.
Also, you are Setting the Boarder, you need to Get it.
