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

@JoeProgram Check this video , i think every thing is good , just the roatation value and the multiplaction of array etc part is at default which you have set , but i think the model should have shown atleast some changes , but its normal no changes are there , and while simulating it disapears and after the pause theres lots of errors

and i have skipped this part as this is to be done if the bones position are not equal , but in my model the distance is equal , am i right ?
