hi, I have copied the extended cut to the tee and triple checked (including the exact test table & query) - the Loop section checking for weekends & static holidays works fine BUT when adding Floating Holiday Dcount coding some of the calculations are incorrect.  E.G 2/10/2023 to 19/10/2023 = 10 days s/be 14;  20/10/2023 to 24/10/2023 = 3 days correct; 21/9/2023 to 23/10/2023 (1 floating holiday of 25/9) =22 correct;  5/10/2023 to 24/10/2023 = 13 s/be 14.  I have double checked that my floating holidays and static holidays are not duplicated.  I have spent hours trying to figure out what is happenning but I now give up - please help
