Another related question if I may.
Using the DateSerial Function above, is there a way to modify it to return the total number of days in the "month" returned?
For example, if the user types the value 10 (numeric) in the parameter [MonthNumber], the function
=Format(DateSerial(Year(Date(),[MonthNumber],1),"mmmm")
returns the string value of "October".
What I'm wondering is if you could modify this DateSerial function to take the same [MonthNumber] value (in this example, 10 (for October) and return the value "31" (the number of days in the month of October?
TIA
