OK, I am probably thinking way to hard and searching. But I can’t seem to find an answer. I am trying to Get a Total from two Amounts via Multiplication. I am very new to Base. I have read that SELECT"A" + “B” method, But no idea where to input that. Any help would be appreciated or links, I just can’t seem to find a proper solution. Thank you much.
