Newbie Question re:Slicing

Hey all,

I’m trying to do a basic slicing of a .wav file in cubase 6.06 I have imported it into the pool. Opened it up in the Sample Editor (double clicking in the pool). Selected the Hitpoint Tab, adjusted the threshold, but when I go to make slices I notice that the “create slices” box is greyed out. So I try to do it via the menu but it doesn’t seem to work either. Also The create Midi Notes is greyed out. I’m sure this is a huge oversight on my part. Please help though.
