If Condition 1 is True, Value 1 is returned. If Condition 2 is True, Value 2 is returned. If all conditions are false, the Else value listed last in the function is applied.
condition 1 (required) Logical condition that returns a result that is either True or False. If the condition is True, the function returns the following value.
value 1 (required) The value to be returned if its preceding condition is True.
condition 2+, value 2+ (optional) Several <condition>, <value> pairs can be listed in a single function. Every supplied condition must have a corresponding value.
else (optional) The value to be returned if no conditionals evaluate as True. If no <else> condition is supplied, a Null result is returned when no conditions are met.
Logical functions test for True/False values. They evaluate a condition, and return a value based on whether the condition is True or False.
