I can scale the top of an object by selecting it's vertex group and hitting 'S'
When I try and scale a vertex group in Geometry nodes it seems to scale the entire object instead of just the selected vertex group.
I have my selection set to the vertex group I want.
and single axis
I've also tried using offset in this link Adjusting / controlling / moving an objects vertex groups using geometry nodes
Still the scaling is not limiting itself to the selected vertex group.
