AND

AND(logical1 [,logical2] [..])

Returns the boolean True or False depending on multiple conditions.

logical1	The first logical value or condition.
logical2	(Optional) The second logical value or condition.

REMARKS

* This function will only return single (aggregated) values so it cannot be used to return multiple values.
* This function is not case sensitive when matching text strings.
* This function does not support wildcards (? and *).
* This function does not use short circuiting evaluation.
* This function will return True if all the logical arguments are True.
* This function will return False if all the logical arguments are False.
* The logical values can be constants, logical equations, cell references or named ranges.
* Any numbers (except 0) are True.
* Any empty cells are ignored.
* If any argument does not evaluate to either True or False, then #VALUE! is returned.
* This function can be used to check if values meet certain criteria.
* You can have a maximum of 255 arguments.
* You can use the IF function to return a value based on whether a condition is True or False.
* You can use the OR function to return the logical OR for any number of arguments.
* You can use the NOT function to return the opposite of a True or False value.
* You can use the XOR function to return the logical exclusive OR for any number of arguments.
* The equivalent VBA operator is VBA.AND
