I mean, i have a fuel tank. It only have a counter that shows the total of litres that have been extracted from the tank.
First day , i fill it with 1000 litres (for example).
After this, i have a web form where my users fill it with the data of each refill they do.
They have to add: date, driver’s name, vehicle,… and the number of litres that the tank’s counter show.
Then if i can recover the final value of the counter for the last record, i can avoid to entry this number again and laso i can check if it has been any refilled that has not been recorded.
Then …. Is there any way to recover the value of a field of the last récord and prefill another field with this value for the new récord?
Thank you for your time.
