Overview of Project functions
When you use Microsoft Office Project Professional 2007, you might need to work with values that do not reside directly in fields. Formulas enable you to work with fields to create these new values. To learn more about how to use Project functions, see the Guide to expression syntax. This guide is written for Microsoft Office Access 2007, but can be used with Project 2007 to understand how to work with functions and custom fields.
The following examples illustrate how you can use formulas with custom fields:

When added to a custom number field, the following formula returns a numerical value that indicates the number of days between the current date and the finish date of the tasks in your schedule:
DateDiff("d",NOW(),[Finish])

When added to a custom text field, the following formula returns a value of "No baseline," "Overbudget by 20% or more," or "Under budget":
Switch(Len(CStr([Baseline Finish]))<3, "No baseline", ([Cost]+1)/ ([Baseline Cost]+1)>1.2,"Overbudget by 20% or more", ([Cost]+1)/([Baseline Cost]+1)>1, "Overbudget",True,"Under budget")
