Trying to fine the shape drop down in geometry

I am following a tutorial on making a christmas tree, The users adds a tree, bevels it and the turns up the resolution. so far im following ok, then he goes into the geometry options and goes to shape and gives all the tree branches a cone shape so it actually looks like christmas tree branches. When i try to do this there simply is NO shape option in geometry options… Where can i do this?

So what tutorial and what where in the tutorial are you having problems ?
