So if this was done with just bubble you could have a date range and once an evening has passed and you add a new one, the evening that has passed will no longer show. It will start be in the DB but just will not show on your RPG.
How do you do that ? I’m now using only bubble, I recreated the table that I had in airtable, and (even if I still need to accommodate a bit) it works great. Well I’m at the same level than before. But for now item#1,2,3 are related to Row#1,2,3. That’s a step for me 
Now how could I tell in the data source field that I want :
The first group/Block related to the 3rd last row in the data base
The second group related to the 2nd last row
And the third group to the last row ?
I’ve been trying to understand the data link in the data source field but for now it’s too complex for me.
Thanks !
