Błąd, odniesienie do zmiennej przed inicjalizacją

Nie wiem czemu ten widok zwraca mi blad: local variable 'user_to_find' referenced before assignment. Chcialem zarejestrowac uzytkownika w tym widoku ale mam ten blad.

def register(request, page=0):
    page = 'register'

    if request.method == 'POST':
        email = request.POST.get('email', '')
        password = request.POST.get('password', '')
        password2 = request.POST.get('password2', '')
        first_name = request.POST.get('first_name', '')
        last_name = request.POST.get('last_name', '')
        address = request.POST.get('address', '')
        postCode = request.POST.get('postCode', '')
        city = request.POST.get('city', '')
        phoneNumber = request.POST.get('phone-number', '')

        try:
            user_to_find = User.objects.get(email=email)
            cartAutho = CartAuthorized.objects.get(user=user_to_find)
        except ObjectDoesNotExist:

    return HttpResponse(t.render(c, request))
