Question

Is the sentence correct?
She is attributed to his success. 
If the sentence above is not correct, please help me to correct the mistake.

Answer

It isn't her that is attributed, it's his success. The sentence should be something like "his success is attributed to her".

Answer

He attributes his success to her. Means he thinks he is successful because of her, because of something she did.

Answer

It's unclear what you mean. It would help if you say who was successful, and who helped.
