Not sure what I'm missing.
What you are missing, I think, is defining your problem! You have
fallen into the error that is not at all uncommon amongst
enquirers. You have shown us a formula which you tell us does not
work. You have not told us what you were hoping it would do for you,
leaving us to guess from the formula itself. But the one thing we
can be absolutely sure of - we have your assurance for this - is that
this formula does not define what you are trying to do, since it does
not succeed.
In any case, I don't know what regular expression you think you have
supplied here: the asterisk is used to match zero or more of the
character preceding it. There is no character before your first
asterisk; as regards the second, are you expecting a match for
*regressio, along with *regression, *regressionn, *regressionnn, and so on?
The IF() function is a bit of a red herring. The essence of your
formula is the logical expression N200="*regression*". This has a
logical result (which, incidentally, is identical to the result of
your IF). But there is no facility to invoke regular expressions in
the logical "=" operator: it will give the answer TRUE (or 1) if and
only if the two operands are equal. So you should get TRUE or 1 if
N200 is exactly "*regression*" and FALSE or 0 otherwise.
There are a number of functions which allow regular expressions (see
the help text), but "=" is not one of them.
I trust this helps.
