The values that can be displayed in a cell as a result of an invalid entry or invalid formula are as follows:
This displays when a formula includes a division by zero or when a formula uses, in the divisor, a cell reference to a blank cell or to a cell that contains zero.
This displays when a value is not available to a function or formula.
This displays when text in a formula is not recognized or when the name of a function is misspelled, or when including text without using double quotation marks. This can also happen when you omit a colon (:) in a cell range reference.
This displays when you specify an intersection of two areas that do not intersect. Possible causes include a mistyped reference operator or a mistyped cell reference.
This displays when a number in a formula or function cannot be calculated when a formula produces a number that is too large or too small to represent, or when using an unacceptable argument in a function that requires a number. If you are using a function that iterates, such as IRR or RATE, and the function cannot find a result, this value is displayed.
This displays when a cell reference is not valid or when you deleted cells referred to by a formula.
This displays when the wrong type of argument or operand is used, such as using text when the formula requires a number or a logical value or using a range instead of a single value.
