Webform: prepopulate fields through URL, "page not found" I'm trying to prepopulate fields in a webform from the URL.  I'm using Webform 7.x-3.20.  I have a form named prepopulate. It has a field "First Name" which has the default value set to %get[first_name].  I have tried to prepopulate the field from the following URL:

http://localhost/test_site/?q=content/prepopulate?first_name=miranda


This results in a "page not found" error.  Does anyone know why this happens?

Thanks in advance!

*UPDATE: I've figured out this happens because it is a rewritten URL (Pathauto).  Still don't know how to fix it, though.
Here is the answer.

It seems clean URLs are not enabled in your site. So here I'm giving the solution in both ways

Assuming that your Field Key  for First Name field is first_name

If clean URLS not enabled. 


  http://localhost/test_site/?q=content/prepopulate&amp;first_name=miranda


If clean URLS enabled


  http://localhost/test_site/content/prepopulate?first_name=miranda


I've tested this on my environment and works perfect. Hope this helps
