230,688 PointsConceptually, you might expect this to work since the 2nd assignment of "msg" overwrites the value from the first one. But a variable can only be declared one time, so the 2nd declaration causes an error.
You could fix this by removing the final "let", but removing the first declaration/assignment entirely is a better solution since it is redundant anyway. Either way you'll pass the challenge.
