set up sum with exceptions in numbers
I am creating a chart and need a simple answer. In one column I am entering a number 1-10 and in the 'sum column' I need that number to be multiplied by 57. So that part is easy obviously.
However, if the number is a 5, I need the "sum" to say 260 and if it is 10, I need it to say 500.
Help please!
