Hello to all.
I´m working on a workflow that show information from last month
Now, the information comes from 2 different sources, and merge the data into one result.
That said, I have an issues with the summarize.

As you can see, it shows that if I want to do the sum of a month, I must do it manually.
Is there a way in which the summarize could work automatically? Meaning that when a new “last” month exists it does the sum without someone going to the workflow and change it.
Thank You.
