AND

Returns TRUE if all its arguments are TRUE; returns FALSE if one or more argument is FALSE.
Syntax
AND(logical1,logical2, ...)
Logical1, logical2, ...    are 1 to 30 conditions you want to test that can be either TRUE or FALSE.
Remarks

• The arguments must evaluate to logical values such as TRUE or FALSE, or the arguments must be arrays or references that contain logical values.
• If an array or reference argument contains text or empty cells, those values are ignored.
• If the specified range contains no logical values, AND returns the #VALUE! error value.
