    NA in date field (MS Project 2000)

    I am attempting to create an IIF statement in a custimized text field. I am using the [Date1] field in the expression where [Date1] may have a date entry or not. IF it does not the [Date1] field has NA put in the field The formula I am using is
    IIF([Date1] is NA, do something, do something else)
    I get errors with this formula.
    How do you handle a NA in a date field when you want to use this in a formula?

    Re: NA in date field (MS Project 2000)


    The issue at hand is that the Date1 field is treated as a Date field. When you don't enter a date, the field is written as NA. Testing for = NA or is null or other tests will give you the #Error. I can't remember how to test against this to make it work.

    A workaround is to go to Tools, Customize Fields, select the text field you are using, select the Value List and set the default to some silly field such as 12/25/1988. (Dont forget to unrestrict the field) You can then test against the field you set as the default to get your test to work instead of testing against NA.
