django-'NoneType' object is not callable

I think this is your issue: You are using a FormView but haven't defined a form class to use. Either set a form_class attr on the class, or override the get_form_class method:

class ReulstView(FormView):
    context_object_name = 'result_list'
    template_name = 'result_list.html'
    model = Result
    form_class = InputForm

Also, the form_valid method will receive the form instance, you don't need to instantiate it manually:

def form_valid(self, form, **kwargs):
    form = InputForm(self.request.POST)  # <- remove this line
    if form.is_valid():
    ...

Lets make another thread. :) The only way you can get "return outside function" error - you are trying to return something not from function. :) It could happen usually because of misstype or wrong indentation. Could you please provide the code where you get this error? I believe that there is something wrong with indentation there.

class ReulstView(FormView):
    context_object_name = 'result_list'
    template_name = 'result_list.html'
    model = Result

    if form.is_valid(): # <- it is not a function or method
                        #  it is a class declaration  
        company = form.cleaned_data['company']
        region = form.cleaned_data['region']

        self.queryset=Result.objects.filter(region=region)

        return render(request, 'result_list.html', {'form': form})
     def get_context_data(self, **kwargs): #<- and this is a method
        #... all your following code

I'm not familiar with Django FormViews, but looks like correct code could be like this:

class ResultView(FormView):
    context_object_name = 'result_list'
    template_name = 'result_list.html'
    model = Result

    def form_valid(self, form):
        company = form.cleaned_data['company']
        region = form.cleaned_data['region']
        self.queryset=Result.objects.filter(region=region)    
        return render(request, 'result_list.html', {'form': form})
