New to AS3

Hey I’m doing something for my work, i know its actually quite easy for a vet but I’m just a beginner here. The point of the script is to have an interactive map for a building that when you click on the location it highlights and stays on the screen for x amount of time along with some text about the location. I have completed all of the following and I’m now trying to refine it some more. At this moment I only have 3 diff. locations to click, its all a mock anyway because they haven’t handed off to me the real assets. I have it right now that when you click a location, the highlights from the other locations disappear, leaving only your current selection highlighted. However in order to do this I have to go through and systematically turn the other off in the code, not that bad with 3 but there could be 20 locations on the real map, I honestly don’t know. Anyway I looking for a cleaner way to do this, and have it be simpler. Please take a look and let me know what you think.
