Pessoal, alguém sabe como é possível fazer uma frequência acumulada com incremento? Quero pegar o valor da linha anterior e somá-lo com o incremento que escolher (+1, por exemplo). Abraços! ---

Hi Samuel, welcome to the community! I assume you’re adding rows either with a form or an add row action. Let’s call your incremental column “Number”. You will have a “Next Number” column that is a math column with the formula Number + 1. Point the Number part to the Number column. When you use an add row action or a form, use a screen value (if you’re writing new rows from a details view), point to the “Next Number” screen value and write to the Number column for the new row. If you’re adding from a list view, you may want to create a rollup column instead to take the max number from the “Number” column, then use the same “Next Number” approach above. ---

Olá, obrigado pela rápida resposta. Com a imagem abaixo, gostaria que ocorresse a soma entre a linha anteior (5) “ORGANIZAÇÃO” e o incremento escolhido (por exemplo, 2), resultasse em 7 como o dado da primeira linha da mesma tabela. Ao invés de apenas utilizar o incremento 2 isolado, gostaria que ele fosse somado com o resultado da linha anterior. ![image](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/9/d/9dc05ba9cf6d6ec687ea3a2019a4e3a58fde20e3.png) Abraços! ---

@Lucas_Pires or any Portuguese/Spanish speakers, can you help with this case? I’m not entirely sure about the translation. ---

The “ORGANIZATION” column receives data from an increment via a button. For example, in the last line of the “ORGANIZATION” column in the image above, the data is 5. In the next line, in a form, I will enter a specific increment (2, for example). I would like the data on this line to be 7 (5 from the previous line + 2 from the new increment) and not 2 as it is being registered (only the increment is registered). Thanks in advance! ---

So what you enter in the form is the increment, and then you want to retrieve the value from the previous row to have a final sum between the two? ---

That’s right!! ---

Then what I would do is: - Add a rowID column if you haven’t done so. - Add a “previous rowID column”. - Use the current rowID’s column (if you add it through the details view) to set to the new row’s previous rowID column in an add row action/form environment. - If you use a list view, retrieve the last rowID through a single value column, then do the same thing as above. - Through the previous rowID column, make a relation and a lookup to retrieve the previous row’s “number”. - Use a math column to sum the number retrieve above with the increment number you add through the form.
