In spite of my deep love and respect for AS3, it is nagging me with an error message in spite of the fact that the interactive in question appears to work perfectly. The interactive is fairly simple. I have a map showing the locations of all local golf courses. You click on those locations and a big golf ball pops up with detailed info. All the golf course movieclips are in the library and brought on stage with addChild. It works great, but I’ve run into a snag. If a button on the map is clicked I need the previous movieclip to disappear. I’ve manage to do that, but I get the error message below. Below that is the code. I’ll put a line in caps indicating the line of code that seems to be not quite good enough to suit Mr. AS3.
The line will read: [COLOR=“Red”]HERE IS THE FUNCTION THAT REMOVES THE CLIP ALREADY ON STAGE[/COLOR]
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
