Django - Add two names - Couldn't print results - django

Question

I'm new to Django.
Trying to build an app that adds two names. Pretty Basic.
Built a page that collects the names but not printing the final result.
Here is my code:
urls.py - inside the app
urlpatterns = [
path('',views.home, name='home'),
path('add',views.addname,name='add')
]
views.py
from django.shortcuts import render
from django.http import HttpResponse
def home(request):
return render(request,'input.html')
def addname(request):
val1 = (request.POST['fname'])
val2 = (request.POST['lname'])
res = 'Hi' + val1 +val2
return render(request, 'resultprint.html',{'resultprint':res})
templates/input.html
{% block content %}
<h1>Hello!</h1>
<form action='addname' method='post'>
{% csrf_token %}
Enter 1st name : <input type='text' name='fname'><br>
Enter 2nd name : <input type='text' name='lname'><br>
<input type='submit'>
</form>
{%endblock%}
templates/resultprint.html
{% block content %}
Result: {{resultprint}}
{%endblock%}
Below are the screenshots:
Couldn't really find where is the mistake happening.
I added the templates and app in the Settings file.

You have to set the same url in your urls.py :
urlpatterns = [
path('', views.home, name='home'),
path('addname', views.addname, name='addname')
]
But you can use directly the name of the url in your html file like that :
{% block content %}
<h1>Hello!</h1>
<form action='{% url 'addname' %}' method='post'>
{% csrf_token %}
Enter 1st name : <input type='text' name='fname'><br>
Enter 2nd name : <input type='text' name='lname'><br>
<input type='submit'>
</form>
{%endblock%}
