Change False?

Is it possible to do something instead of "False" in the formula, for example, an empty cell or the text that I want to introduce?
e.g. in the formula = IF(D =M$2;B2) or others? ;]
greetings ;]

For a text:
Code: Select all   Expand viewCollapse view
= IF(D2=M$2;B2;"The case, when it is not True")


For a VISUALLY empty cell (a cell is never EMPTY, when it contains a FORMULA):
Code: Select all   Expand viewCollapse view
= IF(D2=M$2;B2;"")

ok is working, but what about #N/A?
like COUNTIF(A2:A50; A2)(some like: if true = ok, if flas = " ")
or VLOOKUP(L2;MyTitle;1;0)
or =r2=s2 (as above)
or ISTEXT(a1) (as above)

is working too?

The formula
Code: Select all   Expand viewCollapse view
COUNTIF(A2:A50; A2)

doesn't make a lot of sense since A2 is both the criterion to be searched for and part of the search range. In any case, are you looking for
Code: Select all   Expand viewCollapse view
IF(COUNTIF(A2:A50; A2);"ok"; "")

which will show ok if the COUNTIF returns something other than zero.
Similarly, your VLOOKUP returns a value from the search column. But if VLOOKUP might return #N/A, you can use the ISNA() function.
Code: Select all   Expand viewCollapse view
IF(ISNA(VLOOKUP(L2;MyTitle;1;0));"";VLOOKUP(L2;MyTitle;1;0))

If you want to handle the case of #N/A in B2 and see either a blank cell or ok, use
Code: Select all   Expand viewCollapse view
=IF(ISNA(COUNTIF(A2:A50; B2));""; "ok ")

If you want to see the result of the COUNTIF, use
Code: Select all   Expand viewCollapse view
=IF(ISNA(COUNTIF(A2:A50; B2));""; COUNTIF(A2:A50; B2))

Then you must use more conditions:
There is a function named ISNA(). Use it to determine if an input parameter is valid or not.

The #N/A is an error message, and all error messages, when generated via a formula, take precedence over the normal returns of that formula.
ie: a formula that returns #N/A will show #N/A, rather than the "" you are expecting from your formula.
To include the ISNA function, with your formula, you have to check that first, so your formula could look like
Code: Select all   Expand viewCollapse view
=if(isna(countif(A2:A50;B2));"";"OK")

okey, there is a problem with =if(isna(countif(A2:A50;B2));"";(A2:A50;B2))
there is no #N/A is ok, if it finds B2 entries in column A ... it shows "1" but if it does not find "0" shows.

The question is, why the autofilter does not show 0?
Can I change 0? ew to do so that the autofilter can see 0?

When did autofilter get introduced to this problem?
Autofilter, like all of the filters, shows just the rows that match the filter.
I hate auto-filter and always use the Standard Filter, as I find it gives me much more control over the information to be shown.

Your current problem does not match (any longer) the original topic, so, technically you should mark this one as Solved, then start a new topic with this new problem.
There are several topics regarding auto-filter already on the forums, so I'm going to suggest you check them before starting a new topic.
