I'm afraid posting the database-file will do no good, - it's all in norwegian, and that is why the language in my posts might be a bit odd sometimes....
Let me try to explain my "needs" by asking two questions:
1. Is it possible to do this automatic creation of invoices? There are three tables involved; member, invoices and line-item, with all the "normal" fields, and some more. I want FileMaker to create one new invoice for each of a selection of members, and to use the same "invoice-text" and amount selected from the line-item table.
2. If it is possible, what would be the theoretical way to do it/ the process? Where to start, what to select, which relations would be necessary, how to create new invoices, etc....
