Changing the field unique name

but how can we add a custom field name ?, because the field name is automatically assigned by jotforms?

for example

https://www.dropbox.com/s/mu2q0jylb0uz1kg/Captura%20de%20pantalla%202017-04-15%2011.21.57.png?dl=0

but I got this

https://www.dropbox.com/s/rxqhr3uskxu8kn0/Captura%20de%20pantalla%202017-04-15%2011.24.21.png?dl=0

is there any way to change this ?

You can change the Unique Name in the Properties of the form field.

If you look at the source code from the Chrome DevTools, you'll see "q5_newText" as the name of the input.

Hope that helps. Thank you.
