I think I'm doing it wrong

/click [button:2] GWEENBM RightButton; [button:3] GWEENBM MiddleButton; [button:4] GWEENBM Button4; [button:5] GWEENBM Button5; GWEENBM

Are the spells that are associated to these buttons need to be on there?

No, GS creates those buttons as it creates the macro, you see that on the /m but ignore it from there and it will still work fine

Thanks it gets confusing
