Hello

I am trying to make a formula for counting down a number when i make an entry in a sheet. Anyone know a good solution for this?

I need it to take a number i choose, or a static from one collumn , and then take - (minus) the number added in a specific column in the sheet.

So when entry Column A = 50 pieces static, , Column B= -3 pieces , Column C=47 pieces left.

I tried following the Stock example app, but i had problems the formulas not showing in the â€śunder the hoodâ€ťâ€¦ i dont know whyâ€¦

Thanks guys! Enjoy summer !
