I still do not get what I want, I came to the conclusion that
1.My data is saved in TinyDB
2.Created in tables
I came to the conclusion that it is the tags that need to be taken away, correct me if I’m wrong

Did you test my aia? In this post.

#47

yes, but when you press the button, it takes away only once

#49

you need to take away constantly when you press the button

Table1, 80 table 2, 300
On button click it gives you 220

You again on button click Is it need to subract 80 from 220, and the result to be 140, then 60???

No need to shout, if you have seen the code, that part was missing because I had to redesign how tinydb works. Now it should work

If it works for you then don’t forget to mark solution :white_check_mark:

#59

and with one tinyDB it can be done?

#60

Yes it can be done since tags are different, used two components to make it easier to understand the code.Both actually use same namespace tinyDB1 if you check properties
