I'm trying out this formula
Code:
{=SUM(IF(FREQUENCY(IF(Blad2!$N:$N="<"">",Blad2!$B:$B),IF(Blad2!$N:$N="<"">",Blad2!$B:$B))>0,1))}
To try and get all the unqie values in column B when column N is blank.
I have similar code for when N is not blank, it it works fine.
Code:
{=SUM(IF(FREQUENCY(IF(Blad2!$N:$N="IS",Blad2!$B:$B),IF(Blad2!$N:$N="IS",Blad2!$B:$B))>0,1))}

Anyone able to tell me another way I can do this?

Press F7 to start spell check in Excel. Be careful, by default, Excel does not check Capitalized Werds (whoops)
I'm assuming column B contains numbers, not texts. If so try something like this

=SUM(IF(FREQUENCY(IF(Blad2!$N$2:$N$1000="",IF(Blad2!$B$2:$B$1000<>"",Blad2!$B$2:$B$1000)),IF(Blad2!$N$2:$N$1000="",IF(Blad2!$B$2:$B$1000<>"",Blad2!$B$2:$B$1000))),1))
Ctrl+Shift+enter

Remark: for the sake of performance avoid references to entire columns like $N:$N in array formulas. Adjust the ranges to suit the expected/likely/desired number of rows.

It still does not count the blank row on my sheet.

I have a summary field that sais
Amount of unique "IS" based of the B column
Amount of unique " " basesd of the B column

So the summary should pickup that I have 1 from B.

Thank you very much for the information on Array formulas. A followup question. Even if my rows can add up to 15 000, it's still better have it ranged? The thing that i'm afraid of is if I DL a new query and it exceeds 15k rows, someone will not pay attention to it and miss valuable information. Would it be better to try and VBA the entire thing?

Try this - observe that i used a big range 2:30000

=SUM(IF(FREQUENCY(IF(Blad2!$N$2:$N$30000="",IF(Blad2!$B$2:$B$30000<>"",Blad2!$B$2:$B$30000)),IF(Blad2!$N$2:$N$30000="",IF(Blad2!$B$2:$B$30000<>"",Blad2!$B$2:$B$30000))),1))
Ctrl+Shift+Enter
