Good afternoon everyone,
I have been trying for a few hours to get a new column that gets me the running sum of a column by client (another column in the same table). I have read other similar topics but somehow I am still trying to figure out how to do it correctly.
Here is a pic of the formula I am using, and as you can see, the results I am getting are the total sum for the whole table in each row of the new column.
I have always worked in financial accounting and just now getting more involved in analytical work so my experience is very low. But thanks to you guys I am learning a lot in this forum. I hope I will be soon in the position of helping other people too. Sorry if my question seems a little amateur like.
Ideally I would like to calculate the running total by client and also by month (so that new column would be 0 at the beginning of every month for every client), but for now I am still trying to calculate it without taking into account the month variable.
Any ideas please?
Sorry for my english (not my first language)
Thank you so much!!
