How can I create a map where text pops up when a number (1-14) is scrolled over

I'm trying to update an interactive map where different text pops up (basically the place name) when a number on the map is scrolled over/hovered on. I believe I need to use coordinates in AA and create an .fla file with some JS coding. I've been trying to find a video tutorial to help me work out how to do this. Can anyone help please? I've spent hours researching this and still don't know to create this outcome.
