In three instances I have used this formula successfully to calculate an age in years: =SUM(J19-C1)/365. J19 & c1 are formatted as dates and the answer cell is formatted as a number. When I try to use the same set up in subsequent cells the answer returned is "#value". If I change the date in one of the problem cells to be the same as in one of the cells that calculates correctly, #value changes to the correct answer. Has anyone got a solution for this?
