Checking instance name (character selection screen)

Hello Kirupa Community. I am trying to make a character selection screen. So I thought the most efficient (for my skill level) was to make a single “selectionBox” class. Then I would add mulitple instances of this class with different names (not through code, just drag them and give them names). then through a mouse event listener, I could go through and check to see the instance names of the “selectionBox” class. Problem is, how could I do this? I dont know how to check instance name.

EDIT: I think I’m leaning towards an array, but I have not the slightest idea how to use that…
