Soul and Self in buddhism

I've heard a lot of questions like, "who is there to enlighten if there is no self?" Is that kind of question based on ignorance on the difference between Soul and Self? Or does Buddhism deny the existence of both Soul and Self? I think I understand Buddhists saying that 'Soul' doesn't exist. I understand the word *atman* meaning Soul in Vedic languages: and it is different from the concept of Self. While nobody can deny the fact that a person exists, the existence of a soul is not proven. Just curious about the concept of soul and self in Buddhism.
