Hi Ogunsanya, Now I added the same as per your suggestion. Following is my urls.py contnent
from django.urls import path from fusioncharts import views app_name = 'fusioncharts' urlpatterns = [ path('push-data/', views.push_data, name='push-data'), path('home/', views.home, name='home'), path('display_data/<str:component>', views.display_data, name= 'display_data'), path('index/', views.index, name=''), *path**('process_data/<str:ver>', views.process_data, name='process_data'),* ] And my template content (process_data.py)is as follows: <html lang="en"> <head> <meta http-equiv="CONTENT-TYPE" content="text/html; charset=utf-8"> <title>Home</title> </head> <body> <center> <h3>Index page</h3> <table align='center'> <tr><td>Select the version to compare with</td><td> <select name="version" id="version" onchange="location = this.value;"> <option>Select version to compare with</option> {%for ver in version_list%} <option value={{ver}} href="{% *url 'fusioncharts:process_data' ver* %}"> {{ver}}</option> {% endfor %} </select> </td></tr> <tr><td>The current version</td><td>{{version}}</td> </tr> </table> <br><br><br> </body> </html> But now I am getting the following error: Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/index/11.5.1.18900-96 http://127.0.0.1:8000/index/11.5.1.18900-97 Using the URLconf defined in Piechart_Excel.urls, Django tried these URL patterns, in this order: admin/ push-data/ [name='push-data'] home/ [name='home'] display_data/<str:component> [name='display_data'] index/ process_data/<str:ver> [name='process_data'] The current path, index/11.5.1.18900-96, didn't match any of these. Can you suggest now what's going wrong ?
