Question : handling empty textboxes

Hello,
I have a form that adds values for different days up.
depending on data- some textboxes do not get a number inputed into them.
I declare variables like: Dim DayOne As Double
then for each variable I write: DayOne = IsNull(Me.txtDayOne), 0, Me.txtDayOne)
then I finish by saying me.Total = DayOne + DayTwo + etc.........
this works - I am just wondering if this is acceptable code
thank you

Answer : handling empty textboxes

DayOne = IIF(IsNull(Me.txtDayOne), 0, Me.txtDayOne)

davetough,
if it is working why not..

i don't see anything wrong with that...as you describe it..
