New to VBA functions, How do you make your function show the steps to the formula

[dbravo]

For example, in a simple worksheet sum formula it says "Adds all the numbers in a range of cells" When you type SUM then it shows Number1, Number2 ,etc when you get inside the formula. I did a simple function but do not know how to add the same comments on my function. I would like to know how to add instructions to my formula?

Function SUBTRACT(x As Integer, y As Integer) As Integer


SUBTRACT = x - y


End Function
