The REF message is an indication that a data entry error has been made. It is likely that you may not have entered the date the taxi was sold or you have not entered the written down value of the vehicle. Enter the missing items and the REF message disappears on the fixed assets sheet and the profit and loss account which is fed from the fixed assets sheet. I bought the cabsmart taxi driver accounts package several months ago but have lost it as my computer crashed. Do I need to pay again.
