Hello;
for a financial sheet I am trying to find a formula combination.
the scenario goes as follows: if person A ticks a box in column X, a certain amount of due paiment (column Y) will be reduced by 30k (up until 0). The total sum (column Z) that person A will need to pay is the sum of all relevant columns, including the due paiment in column Y (if it's 0, it's 0 euros).
Additionally, the amount that shows in column Y (that will be reduced by 30k if a box is ticked) is a certain percentage of the sum that is shown in column W.
How can I make it so that I only need to fill in the amount in column W, and potentially tick the box in column X, to resolve this calculation? I have tried a few solutions but it'll only make me do as much work as I'd calculate it myself.
Thank you for your help!
