Hi Lloyd. By putting the () around the \w+, I am specifying what the match group is, which means whatever is outside the match group is not returned. After the Match Group I just needed to specify what needs to be found to stop the match group from capturing as "_" and digits are included as word characters. I could have just used [^\w+,](\w+)_  which would mean to stop capturing the work characters once it saw an underscore instead on an underscore followed by a digit"_". I always recommend you try your patterns with multiple examples to ensure that all possible combinations are covered by the regex. FYI, this works as well \w+,\s*?(\w+)_
