I am trying to design a dataform to act as a log of their coaching practice, and for the course they have to have a total of 50 hours of coaching. I have created the form which looks as per the image below, and am using a number field called 'Duration' to record the number of minutes. Each student would add multiple entries.
How do I add up all the numbers in the Duration column below and display this as a total?
Students only see their own entries anyway, so hopefully this would only display their total by default, and tutors when looking at this would filter by name to only show one learner at a time, and again I am hoping the sum would alter accordingly.
Thanks in advance.
