Calculations between rows of a table - Qlik sense

[#1]

Hello,

I try to perform calculations between specific rows of a table to display a customized total but I have some difficulty to realize this, can you tell me if I make the right moves / methods for this, it below an explanatory diagram to make it more meaningful!

The formula is: 100 - ((23492 * 100) / 36073)

Should I rather be on the table or directly upstream of the data extraction?

Or is there an other way yet?

Thank you for taking the time to read!

Cordially.

Would you be able to provide some information about your current dimension/s and expression/s? How many dimensions do you have and what are your expressions?

Ty for your answer !

Sure i extract the data like that from a txt file :

And that is the 3 lines i extrat and use :

(Here its for the value1)

They are in middle of a txt file.

For "intitule" i concatenate 3 column and for the different value i take one column.

I hope ill give you relevant element !
