Whether you are entering the score in shorthand or longhand methods you are able to verify the scores.
In shorthand method at the end of a board the scores you have entered are summed and you are required to enter the total net value. Enter the sum, including the last zero, and press [enter]. When wrong, an error message is displayed. Press [Enter] (for [OK]) and the correct total is shown in the field. Press [Enter] again to proceed.
In longhand the verification is at the score level. For example 4SW10 (4 spades, by west, 10 tricks) is entered followed by the [Enter] key. You are then required to enter the score in shorthand method. In the example 42- is entered (420 for EW).
