Try something like this:

=IF(ISNA(A1),0,1)

Does that help?

Actually I have 1 more question ;-). Let's say that in cell A1 I can have
values "yes", "no" and "#N/A". I wanna set up a formula which will say that
if A1 is different from #N/A then show 1, if not then 0. But there is sth
strange about this #N/A neither of my formulas if(A1="#N/A";0;1) or
if(A1=NA();0;1) works.
