ISERR function

Returns TRUE if the value of cellreference is any error type except #N/A; otherwise, it returns FALSE. The ISERR function is used in formulas that refer to another cell.

Syntax

ISERR(cellreference)

Example 1

Cell	Formula	Value returned
Scratch.A1	=NA( )	#N/A!
Scratch.B1	=ISERR(Scratch.A1)	FALSE

Returns FALSE because the #N/A! error is not recognized by the ISERR function. Use ISERROR to find all error types.

Example 2

Cell	Formula	Value returned
Scratch.X1	="House"	#VALUE!
Scratch.A1	=ISERR(Scratch.X1)	TRUE

Returns TRUE because the #VALUE! error is recognized by the ISERR function.
