Problem with update of airtable's Base id

I tried to search but i didn’t find what i am looking for.

So, i’m working with airtable, but i want to change the base id during my operations.
I try to explain better:

My “customer” select his region(from an airtable), this region is the name of another table with the provinces, and in this last table there is a list of tables to connect(with columns Base id to have all the data of single table).

I can choose the region and the province, but if i try to change table’s Base Id, does not work.

Any suggest?

Of course i know there’s the block

From “airtable” set “base id”

But doesn’t work.

That’s my problem.

Any help would be apreciated
