quite possibly, you need a table "samples" which is Joined to the experiments. You would have the "foreign key" in the new table which would match the "primary key" in the experiments. From there, labels can be printed which show both the "key" and anything unique to the samples.
Thanks so much for your help, this sounds like exactly what I need!! When you say "foreign key", do you mean that the suffix field in the samples table would be related to the unique ID in the experiments table?
When you create a record it should have a PRIMARY (unique) field. When you create the related table, it will also have a Primary field (to make it unique), but it also has a Foreign key field that is _equal_to_ the Primary field value in the Main file.
I suggest you study about relationships and how they work in FileMaker. There are ways to make this Foreign key auto-populate (depending on how the relationship is set up, depending on the layout design).
Okay, so I now have a portal within my experiments layout, which links to the related "samples" table. I added a unique ID number, and when I add a portal record within any experiment record, the unique ID field populates with the unique ID of that experiments, so for example, "b1083". That is great, but is there any way now, to get that to add an additional suffix to that unique ID field, which will then say "b1083-1"?
I would prefer that the suffix start over at 1 for each experiment record, sofor example we would have b1083-1, b1083-2, etc, but when we look at b1090, we would have b1090-1, b1090-2, etc, rather than just serial numbers, such as b1090-1232".
Updated my file It now has both a single table and a two table versions. If want to use either one then I suggest you rename my fields and table(s) to what you have and that way you can import the script(s) with having to edit them. Setup the relationship before you import. (it may or may not help keep things straight)
The single table version (self join) has a couple of more things that have to be done to keep everything straight.
Also you will need two TO of your table if you use the self join relationship. Portal field are from right side TO and the main layout fields are from the left side TO in the relationship in my example.
These work by allowing the portal fields side to make a new record.
