    Conditional Fail Expression

    You can also use conditional fail expressions.

    They look like this:

    expression1 : expression2 : expression3 : ... : expressionN;

    This conditional fail expression may be used for mapping, assignment to a variable and as an argument of a function too.

    The expressions are evaluated one by one, starting from the first expression and going from left to right.

    1. As soon as one of these expressions is successfully evaluated, it is used and the other expressions are not evaluated.

    2. If none of these expressions may be used (assigned to a variable, mapped to the output field, or used as an argument), the graph fails.

    [Tip]Tip

    This expression may be used in multiple ways: for assigning to a variable, mapping to an output field, or argument of a function.
