Thanks for the naming tip, I've been learning FM7 on my own, so I don't know any of the conventions used, I'm just now to the point where I'm knowing enough to ask questions...:
Without the linking table, how do I build the relationship between the two tables to show only related records? I'm not clear on what the keys would be in the case.
What I want eventually is to have a portal on both layouts (Image and Organism) that shows all the related records. So from an organism layout, there are a bunch of images in a portal with a "Go to Related Record" button next to them, so that I can pick out a specific image, and view that image.
I also may need multiple organism related records on the Image page, since some images may contain more than one organism.
Does that change your advice at all? I'm sorry I didn't explain it more thoroughly the first time. But it's very clunky, because you have to choose a serial number rather than a name in the drop-down list in order to create a record in ImageOrganismLinker which contains the serial numbers, which is not very intuitive.
These tables are a smaller piece of a much larger database, but I've run into this problem several times before, and I'm not sure how to solve it.
Thanks again for your response. I will try playing with it to make it work without the linking table like you suggested.
