As i can understand from video, Problem is that first time you submitting the form to /insurance/skydive and second time you trying to submit form to /insurance/skydive/cortionindex url
You have two options:
1) Avoid changing url. Don't redirect to cortionindex, just return necessary view
2) Specify correct action path into your <form> tag
Hi Balu. Sorry for late response.
Inside your controller instead redirecting return View.
