display a selection of a field in a table

[sersal10]

Hi all,

I have a dashboard with a filter of the field event_name and I selected all the events with the words amnesia 2024 in it. But I need to create a table to display all the events with the words amnesia 2023 in it. How could I do it?

Just in case it helps, I have 2 fields called event_code and a previous_event_code so the events of 2024 and 2023 are related that way.

I tried this but didn't work: 

={<year_event=, month_event=, event_code=p(previous_event_code), event_to_compare=, event_name= >} event_name

Many thanks!!
