Select list item: Attempt to get item number 2 of a list of length 1: (Text for Label7)
Note: You will not see another error reported for 5 seconds

make sure you have cleared all the items from the tinyDb and start from the begining

it is necessary that the result remains in the tables

It means ? I have used the label9 for cross checking

thanks for your work, but I need the numbers to change in the table itself

No, see your logic, there problem is there

anyhow let me think about it

no, there are two tables, subtract data from 1 table and see the result in the second when you press the button so that the data is subtracted

For example
Table 1
table 2
result when the button is pressed
table 2
gsk1 = 10

Not sure why this is so difficult, appears trivial…
