Sorry, no, since you attached a binary which will removed by the

First - questions are a lot easier to answer if you only include the
code you are having trouble with and include it in you post - not as an
attachment.

You are trying to evaluate a Boolean expression ( if A<>B or C). This is
something that the CASE statement can not handle. Maybe this will work-

                       7 : Lose;
            PlayersPoint : If Dice_total_Value = Playerspoint
                             Then Win
                             else if (Dice_Total_Value <> 7) OR                                Playerspoint
then Play_Again;
