Not function

Returns the Not of the logical value of an expression. If the value of expression is true, the Not function returns a value of false (0). If the value of expression is false, the NOT function returns a value of true (1). A numeric expression that evaluates to 0 is a logical value of false. A numeric expression that evaluates to anything else, other than the null value, is a logical true. An empty string is logically false. All other string expressions, including strings that include an empty string, spaces, or the number 0 and spaces, are logically true.
