    Oh hang on, ok there was no check to see if the comma was followed by a bracket, so if there was no close bracket, it would replace every comma to the right of the open bracket, which technically would be incorrect because the task specified there to be a following bracket and a single bracket by itself would not count. However as long as the two brackets are there it works fine.
