FORMULA LANGUAGE
Examples: DEFAULT
These two formulas display the value in the field named KeyThought, if that field exists; otherwise, the value in the field Topic is displayed. Using DEFAULT lets you write a simpler formula that is less prone to error, and easier for others to understand.

@If(@IsAvailable(KeyThought);KeyThought;Topic);

and

DEFAULT KeyThought := Topic;
KeyThought;
