Please help me to solve this

Hi,

It's easy. Set the following URL as thank you URL on your first form.

http://www.jotform.me/razwanferdous/redirect?hello={fullName4}

That means, when someone submits your first form, the name will be populated to the second form. This process is called prepopulating fields via URL parameter. Check this guide for more info: https://www.jotform.com/help/71-Prepopulating-the-fields-to-your-JotForm-via-URL-parameters

Let us know if you have further questions.

Regards!
