Getting Error with Django Phone Number Form Field

I'm building a Django form that includes a phone number field. I've been referring to these two SO questions to understand how to do it: 1, 2. I've created this form field:

class ContactForm(forms.Form):
    phone = forms.RegexField(
        regex = r'^\+?[1-9]\d{1,14}$',
        #regex = r'\+?\d{10,14}$',
        error_messages = {'required', 'Phone number required'},
        widget = forms.TextInput(attrs={'class': 'form-control'})
    )

I display the field in my template:

<div>
    <label for="id_phone">Your Phone Number</label>
    {{ form.phone.errors }}
    {{ form.phone }}
</div>

I understand what the regexes are doing and they look correct to me. However, I'm getting this error if I use either one of them:

ValueError at /business/contact/
dictionary update sequence element #0 has length 8; 2 is required
...
Exception Location: /srv/http/example.com/venvs/dev/local/lib/python2.7/site-packages/django/forms/fields.py in __init__, line 125
(stacktrace...)
widget = forms.TextInput(attrs={'class': 'form-control'})
super(RegexField, self).__init__(max_length, min_length, *args, **kwargs)
super(CharField, self).__init__(*args, **kwargs)
messages.update(error_messages or {})
(end of stacktrace)

Can anyone see what's causing this error? It seems to be caused by the regexes.

I just discovered the error. It's in this line:

error_messages = {'required', 'Phone number required'},

I needed to replace the "," with a ":":

error_messages = {'required': 'Phone number required'},
