Good morning, I am working on a pay spreadsheet for myself. I work 24 hour shifts with 2 different pay rates. My goal is to have both of my columns equal 24 hours each day, but put my hours in one of the cells and the other automatically adjust the daily hours. Currently I have my on-call block as -24 and formatted so the numbers are white when negative and my work block as 0, but I'm not sure how to fix it so my on-call block shows as a positive number when I add any number into my work column. Additionally, I had it set up to add in my pay on the bottom of my spreadsheet, is there any way to only add the positive numbers and ignore the negative?
