I'm using a table for total, paid and remaining costs. I need to know how to set el 'RemainingCost' feild to be the 'TotalCost' -(minus) 'PaidCost' using expression builder. or if i can do it without the builder. i just need to know how to write an expression using operators only and not functions like excel when i can subtract two cells' values and i set a third cell to be the result.
