Adding up values from Entry Fields

iain_c

I'm a new Lectora user, so forgive me if this is an easy fix. Also, Hi everybody! I did some searching around and couldn't find an answer...



I'm using Lectora Inspire.



I have a page with entry fields where the user types in numbers. At the bottom is a text field that displays the sum. Right now I have an action group tied to On Select/Change for the entry fields that adds the numbers and changes the contents of the sum field. But the action group fires on each digit typed in. So 11 becomes 12, 34 becomes 37, and so on.



I think that if I created a button that calculated the sum that would get around the problem, but I think there has to be a way to make it work without adding a button.
