How old was Ahaziah when he became king?

[tonychanyt]

22 according to 2 Kings 8:

26 Ahaziah was twenty-two years old when he became king, and he reigned in Jerusalem one year. His mother’s name was Athaliah, a granddaughter of Omri king of Israel.

But then, elsewhere in King James Bible, 2 Chronicles 22:

2 Forty and two years old was Ahaziah when he began to reign, and he reigned one year in Jerusalem. His mother's name also was Athaliah the daughter of Omri.

22 or 42?

Wiki:

Most scholars regard the 42 years in 2 Chronicles 22:2 as a copyist's error for an original 22 years.

Hence, NIV, 2 Chronicles 22:

2 Ahaziah was twenty-two years old when he became king, and he reigned in Jerusalem one year. His mother’s name was Athaliah, a granddaughter of Omri.
