How can i total the values from the multiple text fields to a new field?

Hi 

How to total the values from the field with same question and copy that to new field 'Total'.

It is not possible to perform a calculation with the Multiple Text Fileds widget. If you want to perform a calculation, you will need to use basic form fields.
