    Dim nAge
    Dim dtDOB

    nAge = (Now() - dtDOB) / 365.24

(Substracting 2 date values gives you their difference in Days.  Divide that by the number of days in a year, and you get years...)  If you a nice round number, you can just round that value.

Hope That Helps,

' Returns: lngYourAge is the correct age of the person as of today

Why would you use that huge function when you can do it in one line?  If you really like the "DateDiff" function, then use it like this:

     nAge = DateDiff("yyyy", dtDOB, Date())

There is no reason for that function to be so much code.
