Excel 2007 AND Function

The AND function is one of Excel’s Logical functions. Like other logical functions, the AND function gives only a TRUE or FALSE answer.

To determine whether the output will be TRUE or FALSE, the AND function evaluates at least one mathematical expression located in another cell in the spreadsheet.

The syntax for the AND function is:

= AND ( logical-1 , logical-2 , ... logical-255 )

logical - refers to the cell reference that is being checked. Up to 255 logical values can be entered into the function.
