referencing previous record in calculation

Is there any way to reference the previous record in a calculation?

I need to compare the text in one field to the text in the same field in the previous record where the order of records changes with each new find and sort.

I've been doing it by running a script to bring the previous value forward and comparing that way, but I'm guessing there's a simpler solution.

Thanks for any help.

Hi

You can't find any alternative way with FMP7 !

A relation based on Get(RecordNumber) couldn't be indexed...

But you can do it with FMP8 and the powerful *NEW* GetNthRecord() function...

Simply this (unstored) calc:

GetNthRecord ( text ; Get ( RecordNumber ) - 1 )

So, what are you waiting for ?
