Hello, forum members, I'm trying to do a programming, but I did not know exactly which blocks to use. I don't want to use buttons to calculate. There are a lot of fruits, but I wrote three examples.
What I want to do is to calculate the automatic result of how many kilograms are entered for the apple. I think I can do this if the values are entered respectively or the values are all entered. But how do I calculate when the kilogram values are entered for randomly different fruits? Or when some fruits are left empty? It also calculates the result when the kilogram price is changed.
Should I use the "when ... lostfocus" block? I'd be very grateful if anyone could do a simple example.
