Very informative, thank you.
But is there a way to get rid of redundant datas contained in a field? Is there a way to tell what is contained in a fiel when one is in FMP, other than exporting the data.
I think I will add the redundant field back into the list (in your example I would make 'batt' re-appear in the list), and then I would deselect this erroneous selection wherever it appears.
Then I would go back to the list and delete 'batt'.
Does that sound like a fair solution to you, or do you have a better one? I am going to try that, as it might do the trick. If it works, this is thanks to your explanation.
