Input Value: False

False Gets the Boolean value of false. Result: False
If Returns one of two values (Boolean condition, True, False) based on a Boolean condition. Nested expressions are allowed up to 7. Condition: True

The Not function changes false to true and true to false. Returns a true value if the condition evaluates to false and a false value if the condition evaluates to true.

Condition: True

Xor Performs an Exclusive Or operation on two Boolean values, returning true if one and only one of the values is true. Value: True
Value: True

Yes Gets the Boolean value of true. Result: True
The True value and False value inputs need to return values of the same type. For example, dragging a SmartBox SmartObject Delete method into a True Value will be allowed by the If’s Input wizard, but it will not work at runtime because the Delete method does not return a value.

The Function Wizard content varies according to the selected function:
