[HELP] Alt-S "Shrink/Flatten" Not working - v2.77

Hey, Im currently making a pineapple grenade as my first project and If i try to use Alt-S nothing happens It just scales the mesh.

Im using Blender version 2.77.

It works as expected for me. https://www.blender.org/manual/modeling/meshes/editing/deforming/shrink-fatten.html?highlight=shrink
