code above, loaded obj loadobj function, why cannot remove "frame" chair01?

i have tried method,if didn't load obj via loadobj funtion, can remove frame chair01

the car "frame" sent parameter loadobj, presumably undefined still. , frame never defined after that. edit: due scope closure on parameter. need object maintain persistence.
