since A1 is 3300 , A "X" will show up in C2
C2? Don't you mean C3?
Also, you're overlooking the interval overlaps.
C1 I want a "X" if A1 is less than 2300
C2 I want a "X" if A1 is between 2300 and 3000
C3 I want a "X" if A1 is between 3000 and 4000
In the above, you're *excluding* 2300, 3000 and 4000. If A1 = 3000 then what
result do you want?
3000 is not less than 2300
3000 does not fall *between* 2300 and 3000
3000 does not fall *between* 3000 and 4000
Typically, when people say "between" what they really mean is >= and <=.
Is that what you meant?
