Group Email Challenge Task 1: Multiple lines not creating a regex object

I've tried this a few ways and I've debugged down to the code below, which is not creating a regex search object.

What I've found is that either group, by itself, does return some regex object (or at least is recognized as not having both groups). But, with both included, the regex object is not being created. Feeling stumped, but I want to get on the right direction again.

Note: I didn't include the Multiline flag and components, but this seemed permissible since I'm not searching for all the parts of the string: just these 2 email and phone pieces. Please correct me if that's wrong!

emails.py 
import re

string = '''Love, Kenneth, kenneth+challenge@teamtreehouse.com, 555-555-5555, @kennethlove
Chalkley, Andrew, andrew@teamtreehouse.co.uk, 555-555-5556, @chalkers
McFarland, Dave, dave.mcfarland@teamtreehouse.com, 555-555-5557, @davemcfarland
Kesten, Joy, joy@teamtreehouse.com, 555-555-5558, @joykesten'''

contacts = re.search(r"""
(?P<email>[-\w\d.+]+@[-\w\d.]+)
(?P<phone>\d{3}-\d{3}-\d{4})
""", string, re.VERBOSE)

You left out what comes between the email and the phone number. Remember, once the pattern starts matching, it has to be correct until it stops (that was why we didn't match some of the lines in the video when we were just starting)

Aaaah, I see! So, for example, if I wanted to grab just name and number from that challenge string in one regex expression, I'd have to describe the email pattern in between to get there.

Thanks!!
