FileMaker s different than a spreadsheet. You can have a table for your Display records and a related table for Modules. You can connect 1 module or 1000+ modules to a display with a relationship.
Same basic thing for the modules and graphics.
This kind of import takes a little work. Import the spreadsheets and build the relationships with a script. If you have samples of your actual data that would help to understand where you are headed.
The delimma I'm having that is making me use storage is I have a relationship between Modules in Modules in both tables. What I need is when you type in a display or use a pulldown I need the list of the graphics to show for the modules that are in the display.
Display1 Display2 Module1 Module2 Module3
Module1 Module2 Graphic1 Graphic3 Graphic5
Module3 Module3 Graphic2 Graphic4 Graphic6
Select Display1 or Display2 result shows
Easily done except for the direct image import from spreadsheet, but
doable. You might need to modify your spreadsheet with a few extra
columns to make it go smoothly.
