"place it under it?"
What do you mean? I am putting it into my useable inventory, hit the buttons, and can see the icon appear on the screen. when I go to place it, I am being told I dropped it or I can't place it because I am jumping.
I guess what I am asking is... once I have it in front of me an it is blue and I can move it around, how do I permanently place it to use it?
