3ds Max Bones not showing in "select from scene"

Hey all!

So, the bones showed up at one point in the beginning. But now no matter what I do the bones NEVER show up when I try to find them with the skin mod. I’ve searched and searched for two days trying to un $#@$ this. However, I’m down to my last strand of hair. Can anyone PLEASE help me figure out why the hell the bones are not showing up in the select from scene screen?!?!
