The program has two catalogs with types of orders: finished and not finished.
In which directory to give an order, the driver chooses from the "enam buttons".
There is a total sum field.
What formula should be written so that the enam field cannot be selected if the total sum field is less than 1?
Example:
[Finished] [Not finished] //Buttons
[0 ] //Text field
And I can't click on finished because the number field is empty (need it)
