Next, in the Blank KeyFrame, draw a picture, insert an image or write something. This part of the button WILL NOT be seen by the user. It is the area the mouse must roll over or click to make the animation interact.
So, we need copy this image, go back to the Scene, create a New Layer and paste the image. You must place the image in EXACTLY the same place. Double click the button again, go back to the Hit KeyFrame and check they are lined up.
