Hi Alexander,

you are almost there. In the string you can see that the emails and phone numbers are separated by a comma and a space, so you need to include these in your matching pattern (outside of the groups).

Thank you Christian! So funny thing I had the correct code but I continued to get an error saying not correct regrex Then I realized that all I had to do was add was remove s from the group name email.

For the second part of the challenge I found that ?$ does not have to be outside the group. Initially I was putting (?P<twitters>@[-\w\d]+)?$ and always received a message stating that I did not find all the twitter tags. So I changed it it to (?P<twitters>@[-\w\d]+?$) and it worked.

Regardless, Thank again for your help!
