fixed a typo in naming the function that maps requests to corresponding views.

lancedamalerio_music/About/urls.py

 from django.urls import path
 from .views import Index
 urlpatterns = [
-path('', aboutIndex, name='aboutIndex'),
+path('', Index, name='Index'),
 ]
 # This might be needed, depending on your Django version
 app_name = "About"
\ No newline at end of file
