Use it like a real elevator. Press only one button at a time, then wait for the doors to open to be sure of no glitches, which will hopefully not occur. The random button might cause some if you press the button before the doors open due to the nature of the scripting, but it's the only way to get a good random button in. Press the random button (R) to go to a random floor! (You'll still need to close the doors using the close button though for realism.)
