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

=sumproduct(or(targetcells=Crierion1,and(Targetcel ls=criterion2,targetcells=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.
