Calculation on above Dimensional Value

[#1]

Hi - I have a straight table and like to check if the dimensional value matches the value above:  I've looked at the Above() function, but this seems to be for expressions and not dimensional values. 

Looking for something like this:

If (Person = Person on Previous Row, THEN Same, ELSE Different)

Eg:

Row	Person (Sorted Alphabetically)	Dimensional Calculation
1	David	-
2	John	Different (to Row 1)
3	John	Same (as Row 2)
4	Johnathan	Different (to Row 3)
5	Steve	Different (to Row 4)
6	Steve	Same (as Row 5)

Help appreciated
