Hi guys

Is there a way to instruct excel to return a different value if the value being looked up exists when using index match?

=IFNA(INDEX('Easy Eating Cous Cous 1805'!$D$16:$D$5718,MATCH('Flavoured Cous Cous 1854'!B16,'Easy Eating Cous Cous 1805'!$D$16:$D$5718,FALSE)),"Not in 1805")

VALUE LOOKED UP IS:

31057

VALUE returned IS:

31057


^^ How can I change the value returned to say: 'Exists'

thanks,

R.
