An error for displayobject--r

Report · Nov 17, 2013

I want to create a two buttons for single function and click the same object to make it dissappear in my web. For example, i click "A" and "B", the screen will show "C"object. If I click "C", C will dissappear. I try to make this by removeChild, but it occurs an error when I click "A" and "B" twice

ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.

The first thing you should do is move the page1Click button out of that other function so that it stands on its own. Then you should move that event listener assignment for page 1 up with the other event listener assignments so that you don't keep adding it each time that function processes.
