Thanks again, and I totally understand. I'm not doing a very good job of explaining myself so I think I'll bow out too :-D The answer will be somewhere in what you and June7 have already given me. I just need to figure it out.
OK, ignore me. It's probably because of these descriptions of your combo:
This means it's bound to tblPlants.Family?
This means it's bound to FName, which you said is in tblFamily because I just assumed "control course" was a typo for "control source".
Maybe you meant rowsource, but they are not the same thing.
Personally, I would not use the same name for a control and a field related to the same table, much less a different table. Nor would I use the name of a table for a field name in some other table (granted, the tbl prefix makes them not exactly the same, but too close). Or maybe I'm talking out of my hat and June7 has it figured out. Regardless, I think you've been given the right advice about 3 times now, and it's just a matter of applying what you've been given. I realize you are struggling with interpreting how to do that, but I'm not being of much help so I will bow out. Don't worry, you are in good hands.
I second the notion. Post a db copy and we'll be able to see how this is constructed.
The more we hear silence, the more we begin to think about our value in this universe.

Thanks again June7, sorry, I've been offline for a few days. It's all good. I don't actually think we were even on the same page. Probably due to my poor explanations of what's going on. But I figured it out myself and it's working fine now :-D
