Need help with 3d max

I am modeling something in 3d max 8(first time) and I have his a bit of a problem as I have been using Bolean pick AandB ang cutting into my shape that way(saw it on a tutorial) but I now am unable to do the as for some reason just cuts the shape out and leaves it hollow. Is there a way to join the nubs or get it back to working with the bolean.
Or yeh if I am doing it all wrong please just tell me.
