AEM form email template - Read repeatable fields

Hi,

We are working on a form where we have a panel with 5 fields repeated 10 times. These fields are text fields and user is supposed to enter values. Now we want to read user entered values of these fields and send in email.

We can read the value in Javascript using guideBridge as follows => guideBridge.resolveNode('parentPanel').instanceManager.instances[2].field1.value;.

But we are not able to read this value in email template. Any pointers will help here.

Sample form screen shot: - 

As you can see the rows are repeated 10 times using repeatable settings.
