Copying the value entered on one field to another

Hello I am building a form that the client has to fill out their name 4 times, is there anyway that once they fill it out once it will automatically populate into the other name fields through out the form?

Thanks 

Yes, it is possible to copy the value of one field to another by using the Update/Calculate Field Condition. Here's a demo form: https://form.jotform.com/62544275127961.

Here's a guide on how I created that form:

1. Create 4 Full Name fields.

2. Click the "Conditions" button in the toolbar.

3. Select the "Update/Calculate Field" condition.

4. Create a condition wherein if the "Name A" is filled, then the value will be copied to "Name B".

5. Create more condition for Name C and Name D.

Here's the result:
