Issue with Henry's Animation Tool

Hey guys, I wanted to use HAT in Gmod, but when I go to animate it says this and nothing happens:

entities/hanim_thread/cl_init.lua:35: attempt to index field ‘?’ (a nil value)
entities/hanim_thread/cl_init.lua:35: attempt to index field ‘?’ (a nil value)
entities/hanim_thread/cl_init.lua:35: attempt to index field ‘?’ (a nil value)
entities/hanim_thread/cl_init.lua:35: attempt to index field ‘?’ (a nil value)
entities/hanim_thread/cl_init.lua:35: attempt to index field ‘?’ (a nil value)

How can I fix this and make it work?

Thanks

Nevermind guys, it seems to be all good now, I just took out HAT 4 and put in HAT 3. And plus I was doing it wrong lol.
