FYI: the purpose of the app is for the person who access it to be able to select the food/drinks he ordered in restaurant/bar.
I created a “Sum” text cell (on the green circle) that displays the total amount that is being ordered. It works by displaying the sum of amounts retrieved from a database called ‘Items ordered’.
Through “Magic text > Database: ‘Items ordered’ > Price > Sum”. It then displays correctly the sum of the column “Prices” from the database ‘Items ordered’. → Nothing to report, it works perfectly, i.e. adding up the amounts works.

My issue is the following:
My clear button is not functioning anymore. The “Clear” button is a trick I created to quickly reset the total amount displayed to the customer in the “Sum” text cell (green circle) to 0.
When demoing the app, if someone clicks on a meal displaying a total (sum) of 35€, clicking on “Clear” used to enable me to reset this amount to 0€ (because the action performed in the DB was “- Sum Prices”, i.e. “-35€”, and if the sum was 67€ then “Clear” would perform “-67€” in the DB. It would take the Sum of Prices and deduct it from the current Sum of Prices, which equals to 0.
Now, clicking on the clear button (i.e. action “- Sum Prices” in DB) shows a “0” entry instead of “-35€” or “-67€”, which doesn’t reset the total to 0, instead it performs nothing at all.
This function used to work a few months ago, we didn’t update anything and now it’s not working anymore. Adalo’s team couldn’t figure it out. Maybe one of you could?
Action behind the button:
Below, what happens in the DB when clicking on 4 times on “Clear” = enters 4 times “0” instead:
