Problem using GetUserOption - not picking up system default

Hi all, using PT8.54.03 on Oracle 11g and getting the following...

PeopleCode

         Local string &DateFormat = GetUserOption("PPTL", "DFRMT");

         Local string &DateSeparator = GetUserOption("PPTL", "DTSP");

         Local string &sDispFormat;

         Local string &postedDate;

         If None(&DateSeparator) Then

            &DateSeparator = "/";

         End-If;

         Evaluate &DateFormat

         When = "D"

            &sDispFormat = "dd" | &DateSeparator | "MM" | &DateSeparator | "yyyy";

            Break;

         When = "M"

            &sDispFormat = "MM" | &DateSeparator | "dd" | &DateSeparator | "yyyy";

            Break;

         When = "Y"

            &sDispFormat = "yyyy" | &DateSeparator | "MM" | &DateSeparator | "dd";

            Break;

         When-Other

            &sDispFormat = "MM/dd/yyyy";

            Break;

         End-Evaluate;

         WinMessage ("Format: " | &DateFormat | " | Separator: " | &DateSeparator | " | Result: " | &sDispFormat);
