Array for Sounds

Hello, I’m having trouble creating an array for my sound wave files. Id like to randomly play 1 of 3 or 4 sounds when attacking so It doesn’t sound so repetitive and robotic. I’ve figured out how to randomize the value of an array but I can’t figure out which variable type will let me select my imported sound waves and place them into an array. Even “Sound Wave” variable type will not bring up any of my files in Array Elements.
Am I selecting the wrong Variable type, or do I need to do something to my sound waves so they can be recognized

That’s not the best way to do it. Just make an AudioCue and put this kind of thing in there:
