Hi everyone,
I started to use AT last week to build a book database (hard cover cartoons), it is a simple database with one table and fields related to one book : ISBN (codebar number), title (single line), picture (attachment), Serie (single select) and volume (number).
So I can have different books that belong to the same Serie with of course each with a different volume number.
I am trying to have a field that give me all the volume numbers related to a Serie to find out if I am missing one in the Serie.
Any idea on how I should proceed ?
