Soft body goals not working?

I heard you’re supposed to make a vertex group, assign it to the verts you want to stay in place, and set it to the goal. So I did that, but the verts i want to stay in place still move.


I did it like the tutorial said to, make the part that doesn’t move 1.000, and the part that does 0.800. Still doesn’t work. How do I fix?
