Relational FileMaker questions

[Brian Sheppard]

For any of you FileMaker polymaths, I have two questions relating to
calculations and portals.

1)
I have a relational database with a one-to-many relationship, and am using
calculation fields to create SGML tags around the text. Is it possible to
create a calculation field in the master table which will gather together
text from various fields from ALL of the related records? Right now I can
only get text from the first of the related records. Any suggestions would
be appreciated... 

2)
I have been using the Paste Special command to generate record numbers for
related records within a portal. Is there any way to get those numbers
into a permanent field within those records. I need to keep track of the
sequence of each of those records, and being able to automatically
generate sequence numbers from the record numbers within the portal would
be a great help. 

Thanks.
