Yes, that's causing the circular dependency error.
As you said: Take the previous step name instead.
Actually: You should take the buffered previous step name:
let
...
#"Personalização Adicionada3" = Table.AddColumn(#"Índice Adicionado","contCHAVE", each fcountif(Table.Buffer(PreviousStepName), "CHAVE", [Índice])),
#"Personalização Adicionada4" = Table.AddColumn(#"Personalização Adicionada3","contCHAVEOR", each fcountif(Table.Buffer(PreviousStepName), "CHAVEOR", [Índice]))
in
#"Personalização Adicionada4"Thanks for the follow ;)
That function works for me (technically). So your error must come from the parameters you've provided.
Can you share your query code or give an example for before and desired after please?

Hi
That's the code, below.
let
...
#"Personalização Adicionada3" = Table.AddColumn(#"Índice Adicionado","contCHAVE", each fcountif(Base_documentos, "CHAVE", [Índice])),
#"Personalização Adicionada4" = Table.AddColumn(#"Personalização Adicionada3","contCHAVEOR", each fcountif(Base_documentos, "CHAVEOR", [Índice]))
in
#"Personalização Adicionada4"Base_documentos = name of the table
"CHAVE" and "CHAVEOR" are the names of the columns I want to countif
Índice = Index (from 1)
Basically I want to add two new columns, one that will be a countif to the column CHAVE (contCHAVE) and the other to be a countif of column CHAVEOR (contCHAVEOR). From that on I'll add another column with a logical test (if then else) so I can in the end apply the exact filter I need.
One thing that I think might be wrong is the third parameter of the function. I am not sure what to place there. In the first parameter I put the table name, in the second parameter I put the Column in which I want to apply the countif, and in the third, well, I put the index column. Not sure, but seemed the right thing based on the excel file I got from the blog of the author of the other post from which I got the function.
Thanks in advance,

Code looks perfectly fine to me.
Does error arise when you click on the step #"Personalização Adicionada4" or at a later stage?
Does the table "Base_documentos" depend on this query?

Hi Imke! You are the BI Accountant, nice to meet you. I follow you on twitter.
Base_documentos is the query in which I am running the code. Is that a problem? Should I place instead of Base_documentos the previous stage of the query?
The error I got is that the moment I close the code editor and the query refreshes to show the two new added columns, they are there, but every single field is "ERROR". When I click on them, the circular reference error message pops up.
So, basically, I need to countif in the very query I'm running and I was using this piece of code. If that's not the kind of function that will give me that, what kind of function would that be?
Thanks in advance,
