i want to make snake Dragon model to follow the spline path

Hey @JoeProgram i got this error and i was not able to fix this one , even though i have paseted the get snake length code in it

found one fix but i dont think thi will work i drag and drop the new get snake length and it looked little different from yours

also do i have to type the names of the bones in the default value of bones node ( the model i have its root bone starts from middle of the model and then the hierarchy goes to the face { i think thats opposite of what it should be, isn’t ? } )so in this case should i follow any order in adding names the bones node or the order doesnt matters ?

heres the dragon
