What I have:
I have values in cells C2:G601
That's 600 rows of 5 cells in each row
The values in the cells come from 43 product ID numbers. Ex, AB1, AB2, CR5, etc.

What I humbly request:
A macro (For Each? doesn't have to be) comparing (=) each cell.value to the cells.values above it, as far above as it needs to go within the range Cells (3, 3) , Cells (LastRow, 7) to find an equal value.

On the first match of equal cell.value
count the rows between each cell value

Offset the Row Count results to Cells (0, 10) For Each cell

If no equal value is found for a cell, then leave the Row Count result in cells (0, 10) blank or " " and go to next cell.

Some cells values will equal another cell value in the row above it meaning there is no row count, the Row Count results should be 0 or "0"

Stop finding equal cell.values after the first match is found and row count between cell.values has been counted and results offset, just go to the next cell

ChatGPT Attempt:

VBA Code:
Sub CountRowsBetweenEqualCells()

'Define variables
Dim rng As Range
Dim r As Long
Dim c As Long
Dim lastRow As Long

'Set range
Set rng = Range("C2:G601")

'Loop through each row
For r = 1 To rng.Rows.Count
    'Loop through each cell in row
    For c = 1 To rng.Columns.Count
        'Check if value of current cell is equal to value of cell above
        If rng.Cells(r, c).Value = rng.Cells(r - 1, c).Value Then
            'If equal, calculate rows between current cell and cell above
            lastRow = r - r - 1
            'Offset results to column 10 for each cell
            rng.Cells(0, 10).Offset(r, c).Value = lastRow
        Else
            'If not equal, set results to blank or ""
            rng.Cells(0, 10).Offset(r, c).Value = ""
        End If
    Next c
Next r

End Sub

The macro above leaves all result cells blank except any cell that has an equal value in the first row above it. The macro gives the result as -1,
it should be 0, since there are no rows to count between equal value cells. It only looks for a match in the row above it when there is a match 2 or more rows above it.

Can someone be kind enough to correct the AI?
 

Excel Facts

Which came first: VisiCalc or Lotus 1-2-3?
Dan Bricklin and Bob Frankston debuted VisiCalc in 1979 as a Visible Calculator. Lotus 1-2-3 debuted in the early 1980's, from Mitch Kapor.
If no equal value is found for a cell, then leave the Row Count result in cells (0, 10) blank or " " and go to next cell.
Some cells values will equal another cell value in the row above it meaning there is no row count, the Row Count results should be 0 or "0"
Stop finding equal cell.values after the first match is found and row count between cell.values has been counted and results offset, just go to the next cell
Some details are confusing to me.

Check my following example and tell me if it is correct:

Try the following macro, maybe it requires some adjustment.
In this case, you should give examples and explain the results you need (use XL2BB tool to give examples)
VBA Code:
Sub CountRowsBetweenEqualCells()
  'Define variables
  Dim rng As Range
  Dim r As Long, c As Long, i As Long, n As Long
  Dim a, b
 
  Set rng = Range("C2:G601")                'Set range
 
  For c = 1 To rng.Columns.Count            'Loop through each cell in row
    For r = rng.Rows.Count To 1 Step -1     'Loop through each row
      a = rng.Cells(r, c).Value
      n = -1
      For i = r - 1 To 1 Step -1            'Loop as far above as it needs to go
        b = rng.Cells(i, c).Value
        n = n + 1
        If a = b Then
          rng.Cells(0, 10).Offset(r, c).Value = n
          Exit For                          'Stop finding equal, just go to the next cell
        End If
      Next
    Next r
  Next c
End Sub

If you need to count previous rows then change n = -1 to n = 0

----- --
Note: The macro runs immediately with 5 columns and 600 records. But if the amount of data increases, let me know to modify the code and do it with arrays, then it will be faster, but with the current amount of data I don't see any problems.

NOTE XL2BB:
For the future, it would help greatly if you could give us the sample data in a form that we can copy to test with, rather that a picture.
MrExcel has a tool called “XL2BB” that lets you post samples of your data that will allow us to copy/paste it to our Excel spreadsheets, so we can work with the same copy of data that you are. Instructions on using this tool can be found here: XL2BB Add-in
Note that there is also a "Test Here” forum on this board. This is a place where you can test using this tool (or any other posting techniques that you want to test) before trying to use those tools in your actual posts.

Wow!

Dante,

It's beautiful. Almost perfect!!

It appears the macro test the value to equal another value within the same column versus last occurrence regardless of column.

Is there a way to modify the macro to count the rows between the last occurence regardless whether it's in the same column or not?

I did try changing x = -1 to x = 0 but that did not give me the result I was looking for.

I appreciate your efforts.

It appears the macro test the value to equal another value within the same column versus last occurrence regardless of column.
I used arrays for the loops.
Execution is immediate for all 5 columns, 600 rows, loop back and search all 5 columns.

Try this:
VBA Code:
Sub CountRowsBetweenEqualCells()
  'Define variables
  Dim rng As Range
  Dim i As Long, j As Long, k As Long, m As Long, n As Long
  Dim a As Variant, b As Variant, s1 As Variant, s2 As Variant
  Dim bln As Boolean
  
  Set rng = Range("C2:G601")                'Set range
  a = rng.Value
  ReDim b(1 To UBound(a, 1), 1 To UBound(a, 2))
  
  For j = 1 To UBound(a, 2)                 'Loop through each cell in row
    For i = UBound(a, 1) To 1 Step -1       'Loop through each row
      s1 = a(i, j)
      n = 0
      For k = i - 1 To 1 Step -1            'Loop as far above as it needs to go
        bln = False
        For m = 1 To UBound(a, 2)           'Loop each column
          s2 = a(k, m)
          If s1 = s2 Then
            bln = True
            Exit For                        'exit loop m
          End If
        Next m
        If bln Then
          b(i, j) = n
          Exit For                          'exit loop k
        End If
        n = n + 1
      Next k
    Next i
  Next
  
  Range("M2").Resize(UBound(b, 1), UBound(b, 2)).Value = b
End Sub

Wow! Just Wow! Works perfect! 100%!
For the life of me I can't wrap my head around how you guys write these macros. I can't express my gratitude enough. You saved me a headache and lots of time. I wish they had a tip jar on this site. Sending my best karma. Thank You Dante.
