countif - Criterion1 OR [Criterion2 AND Criterion3]

I wish to do the following:
=countif(TargetCell or TargetCells, Criterion1 OR [Criterion2 AND Criterion3])

eg: =countif(A1, Criterion1 OR [Criterion2 AND Criterion3])
eg: =countif(A1:A10, Criterion1 OR [Criterion2 AND Criterion3])

How to do?

Thanks.

countif won't work well for this.
try sumproduct()

=sumproduct(or(targetcells=Crierion1,and(Targetcel ls=criterion2,targetcells=criterion3)))

=SUMPRODUCT(--ISNUMBER(MATCH(TargetRange,CritList,0)))

where CritList refers to a range that houses the relevant criteria.

....

That'd work for a single equality criteria, but that's not what the OP
asked. Looks like the OP needs something closer to

=SUMPRODUCT(--((range=Crit1)+((range=Crit2)*(range=Crit3)) 0))

where = is just a placeholder for any of the comparison operators.
It'd be more complicated with text criteria including wildcards.
