VBA Nested IF compare statement

Question

Hi I am newbies about vba. I want to compare and count the cell number that continuously lowers the previous cell however the code just successfully counts 1-2 days and n/a only.

Thanks

data set

  Sub Mars()
   Dim i As Integer
   Sheets("working").Select
   For i = 2 To 111
       If Range("U" & i).Value > Range("T" & i).Value Then

Answer 1

In your code, the're a lot of this construction:

IF A < B < C < ...

This is not correct, it should be:

IF (A < B) AND (B < C) AND (C < ...) ...

For readability reasons, I would advise you the following formatting:

IF (A < B) AND_
   (B < C) AND_
   (C < ...) ...

(The underscore means that the "source code line" is not finished and continues on the next line.)
