From my knowledge, Local_Db are just tables created and used in a sesion. They dont keep values between sessions. All you do is only keeping some references of those tables saved between sessions (as row, column), but when you start another session those are refering to a value from an empty table.
If you want to keep that table filled with values between sesion, you need to put all table in a “stored” variable, as a created object with multiple layers with all values from table.
Or, instead of Local_Db use Airtable Or GoogleSheet that keeps values.
Try to put some “wait 0.001” after each update purple block.
And when im using function to put there some repetitive blocks, i usually use some app variable, lets say “waiting” … just like in the following example
this way the program will prevend going further before what i need to do its done.
Working with data sources is kinda tricky, as @muneer tought me, and program needs a lil time to retrieve/save data from/to it.
@domhnallohanlon Could be an issue with data source column or the ‘update value’ block. Work around was I had to create a new column in the data source and reference the new column in my blocks.
