Changing “This value is required” message

Been trying out Caldera Forms and really like it. Best form maker I’ve seen so far! I only wish it cost a little less for the premium version, although the free version seems to be doing almost everything I need.

Anyhow, I was wondering if there is a way to change the default message “This value is required.” when a user forgets to enter a required field. I wish it was something a little more friendly like “Please answer this question.”
