Since I don't know Greek, I have no way to know what those8 Labels hold or mean.

But in general, people use TinyDB to pass data from one screen to another, like packing and unpacking a suitcase for a trip somewhere.
It's tedious.
If you can use multiple Arrangements, only one Visible at a time, you can avoid that, at the expense of more blocks in one screen.
