I'm very new to coding and specifically to JavaScript.
Im trying to use Apps Script to code my google sheet to automate a financial spreadhseet i am making, here is my problem:
I want to input data in a single row, and have it update the row below, for example i want the range B7:M7 to be my input, so lets say for the sake of simplicity all 12 cells in that row will have the value 50
I then want it to transfer onto the range B8:M8, but if that range is already on 50, then i want it to minus that and make it 0. If range B8:M8 was on 0, then i want to make it -50. I hope this makes sense. Thank you
