IFERROR(value, [value_if_error])
-
value– The value to return if value itself is not an error. -
value_if_error– [ OPTIONAL – blank by default ] – The value that the function returns if value is an error.
Notes
IFERROR(exp1,exp2)is logically equivalent to IF(NOT(ISERROR(exp1)),exp1,exp2). Ensure that this is the desired behaviour.
