# Iserror

Hi,

Could anyone tell me how to put an ISERROR in to the following formula:

=IF(OR(ABS((+C3-A3)/A3)>=50%,ABS((+C3-A3)/A3)<=-50%),"Explanation Required","OnTrack")

Basically, if the value of A3 is 0 I get a DIV/0 error when in fact it should be returning "Explanation Required"

### Excel Facts

Which lookup functions find a value equal or greater than the lookup value?
MATCH uses -1 to find larger value (lookup table must be sorted ZA). XLOOKUP uses 1 to find values greater and does not need to be sorted.

=IF(iserror(OR(ABS((+C3-A3)/A3)>=50%,ABS((+C3-A3)/A3)<=-50%)),"Explanation Required","OnTrack")

Try this:

=IF(A3=0,"Explanation Required",IF(OR(ABS((+C3-A3)/A3)>=50%,ABS((+C3-A3)/A3)<=-50%),"Explanation Required","OnTrack"))

I'm curious as to when this part of the formula could return TRUE?
Code:
``ABS((+C3-A3)/A3)<=-50%``

Code:
``=IF(A3,IF(ABS((C3-A3)/A3)>=50%,"Explanation Required","OnTrack"),"Explanation Required")``
