Returns TRUE if any argument is TRUE; returns FALSE if all arguments are FALSE.

Syntax

OR(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 in 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, OR returns the #VALUE! error value.
  • You can use an OR array formula to see if a value occurs in an array. To enter an array formula, press CTRL+SHIFT+ENTER.
