ActionScript 2.0 :: Close Last Opened Door?

I'm setting up a scenario with 12 doors, each with unique (but not sequential) instance names. I've set up a variable that, when a door is clicked, it takes on the instance name of that door. This is working.When clicked, the door movieclip plays to a midpoint in it's own timeline and stops (open position). You can close it by clicking the now opened door which returns it to frame one of it's timeline.Now, I'm trying to make the next door clicked check first to see if the previously clicked door is still open. If it is, it will make the previously open door play() <----- this will hit the end of the open door's timeline which resets it to frame one > and then play itself and set it's instance name as the new "lastOpened" door variable.I was able to manually do it (trying to avoid overlap with neighboring doors) by just directly referring to the instance names so I thought it'd be as simple as dropping the instance name and referring to the variable.[code]
