Thank you so much. Scrutinizer, your solution is what I was attempting but I missed the 2 at the end, can someone please explain the trailing 2 on his solution?

Instead of using a "g" for global replacement, putting a number "n" there only replaces the n-th occurence of a pattern, in this case the second digit, since the number 2 was specified and the pattern is a digit.
