Just switch the symbols around >= or <= NOT => or =<.

Are U sure there are no 'spaces' in the field: Nom?

We had that already in the past......

You have >=1 so the result is true for every record. Try >1 instead.

It took me awhile to figure it out, but I think you are seeing duplicates on empty cells because you are not checking for empty fields first.

Even empty cells satisfy your current conditions. You ask Ninox to find records where Nom equals Nom. Even if Nom is empty, you are saying if Empty Nom equals Empty Nom then count it. So you will always get a 1 so you will always see Duplicate. You can see this if you add a new column with the following formula:

let myV := Nom;

cnt(select 'Oiseaux famille genres espéces' where Nom = myV)

You will see that all of your records have at least a one.

Will Nom be able to be empty or will it always have data when your db is complete?

In addition, when you added >= 1 that will mark records with only a single instance of Nom to be a duplicate. Is that what you want?

This is what I mocked up in a test db of mine, I've added in your names:

let myV := Nom;
if myV = null then
"Empty"
else
if cnt(select 'Oiseaux famille genres espéces' where Nom = myV) > 1 then
"Duplicate"
else
null
end
end

Remember that all Ninox code has to be in English. Table/Field names can be in any language. Any text that is output can be in any language.

let myV := Nom ;

If myV = null then

"empty" / "blank"<--you can put whatever you want here. you can put "vide"

sinon unless / if not<--this has to be in English and has to be else

if cnt(select 'Oiseaux famille genres espéces' where Nom = myV) > 1 then

"Duplicate"

unless / if not<--this has to be in English and has to be else

null

end

end

Also just noticed in line 2 you have a capital "I" for if. That has be lowercase "i". You also need a colon in front of the equal sign.

if myV := null then

Hi

Can you copy and paste your final code here.

Thanks John

Wow, maybe I need to stop posting. Another mistake of mine. In Line 2, I was wrong to say you need a colon in front of the equal sign. It should read:

if myV = null then

The second image it looks like the formula is working as intended. There are duplicates there.

For the first image can you create a formula column that just has:

let myV := Nom

cnt(select 'Oiseaux famille genres espéces' where Nom = myV)

then what number does it give for Souimanga for example? Does it say 1 or some other number?

can you post, again, the final code for "Formule doublons noms".

Well I am now confused. But at least on the coding front you need to double check your coding.

For the Nom formula you sill have the := in line 2.

Now you say you have two formulas, the picture from April 22, 4:21pm is confusing me. one column says Nom and the other says Formule doublons Noms. So I don't know if the formula is pointing to the correct field. Please go back and double check that the fields and formulas you want to check are next to each other so you can be sure you are comparing the correct data.
