Can this code be changed to this.
If click INPUT (active) then "-" coming out.. If INPUT not have number then "-" is hidden... (click anywhere and can delete manual?)
If is -20 then can delete all -20 Now is empty (but input is active) and starting typing 30 and minus comes with the number.
I don't know it's possible.
My script don't like just - -20 (some number) or empty
