Cannot scale vertices Currently, I am following some tutorials on the blender. On latest tutorial we were supposed to create a little creature here's the photo of what it looks like in development.



I am trying to scale those selected vertices to give a more rounded shape. In the tutorial, the instructor successfully does this, however, when I try the scale tool it does not move the vertices.

Why I am failing on this, but the instructor can successfully do it?

Here are the settings I am using:



Note: I am using Blender 2.77.
It appears you have set the origin to Bounding Box Center.
  Set it to Median Point, and this should work.
