The present singleton run-time message occurs if a token which seems to be a macro token does not begin with either a LanguageTag or a DayValue.
For example, in the token below:
the first character of the token is a *, but should either be a number (DayValue) or a letter (LanguageTag) followed by a number, that is to say [1*2d] or [a1*2d].
Macro tokens in Multiple Holidays Options
This error often occurs when a user tries to add a macro to the tokens before/after each holiday in multiple holidays options, as the user is unsure what to use as DayValue, and therefore does not put anything. In such cases, the DayValue 1 should be used, that is to say, the incorrect token [*2d] should instead be [1*2d].
