How to autofill a field, based on another

[MARIA TERESA357475662zwu]

I have a document in which the "name" field appears several times. I want the rest to autofill when I fill out the first one.

 I have this code, but doesn´t run : 
var v = this.getField("name").value;

this.getField("name2").value = v; 

Can you help me?

Make sure your fields is named correctly, "name" and "Name" are not same.

There is an easier solution, just name all fields same.
