Animation cannot be found despite bieng marked as legacy

i have this issue where it gives me an error stating that the animation could not be found transform.GetChild(0).transform.GetChild(0).transform.GetComponent().Play("Idle"); ive looked around and everybody says this is only possibly ever caused by the animation not being marked as legacy, perhaps im just dumb, but i went into debug mode and checked the "legacy" box for my animation yet to no avail, please help this is getting on my nerves
