Thanks Jason,
but I wonder if the WebAssist has some tutorial to their customers as display data that are related to the three tables. As I said before: the tool "Relational Table Manager" works well for entering data in the table of relation between the two. But I need some guidance on how to do this with DataAssist because I am not PHP programmer but a designer and use the tools of WebAssist to streamline my development process and offer solutions better and better for my clients.
Thanks,
