Hi all

I am stumped. I can do this with a script which sets the fields, but I would like it to be dynamic if possible.

I have a database of documents, there are main documents (eg. 1) and sub-documents (eg. 1.1).

When I sort these documents into date order, I would like the numbers to reflect the order with sub-numbers.

I am trying to find a calculation that will take the value of the previous field and add 1 if it is a maindoc or not if it is a sub doc.

My script basically loops through setting a global field to the documentID and then if the document is a main document it adds 1 to the global else it sets it to the global.

Can this be done with a calculation? apendnth maybe?

Any help would be greatly appreciated.

Zippy,

We meet again, but not over cups steaming php this time!

Here's a thought:

if you build a sorted relationship so each record can see the record prior to it in your found set, this would give a calculation a basis for determining what value to output.

It's been a little while since I had to dig deep into what could and could not be calculated. There may be a problem with calculating from related data like that...

But maybe that will spark some ideas.

Solved (I think).

I have had to use two fields. The first calculates the Main Number and then second appends the sub-number.

I have called the field AutoNumber and it references itself.

Case (

Get ( RecordNumber ) = 1 ; 1;

IsEmpty (SubNumber) ; GetNthRecord ( AutoNumber ; Get ( RecordNumber ) - 1 ) + 1 ;

GetNthRecord ( AutoNumber ; Get ( RecordNumber ) -1 ) )

I then have a field called CalcNumber which is

AutoNumber & If ( IsEmpty (SubNumber) ; "" ; "." & SubNumber)

It all seems to work ok ... now to put it into practice and see how it performs
