Your RegEx needs to discern between the two groups! Repeat this process with the phone_number and email_address RegExes. Once all of your tests are passing, commit and push your work using git to submit. Hints Regular expressions can be confusing and frustrating. You'll only get used to ...
So instead of remembering anything above, you should just switch to always safely escaping regex syntax via regex.
