Dear Expert,

I want to auto generate the S.No in column A5 based on input value. I have to enter the No. of record in column C3(Ex: 3).The serial Number will copy auto column A5 (1),A6(2) and A6(3).

The No.Of record is user Input value.

Can you please on this via Excel formula or Vba?

Thanks
Raj

Hi Raj,

This confuses me: 'I would like to display the 3 combination in one'.

I interpreted this as you want the solution to work for all 3 scenarios.

The code below will fire once you make a change in cell G3:
- Column A, starting at row 6 will be cleared.
- Column A, starting at row 6 will be numbered to the amount entered in cell G3.
- Spacing between the numbers will be determined by how many cells in range C3:E3 contain data.

Here is the code:
```Private Sub Worksheet_Change(ByVal Target As Range)
Dim mStep, NoR, x, y As Integer

If Intersect(Target, Range("G3")) Is Nothing Then Exit Sub

mStep = WorksheetFunction.CountA(Range("C3:E3"))
NoR = Target.Value
x = 6

Range("A6:A" & Rows.Count).ClearContents

Do
y = y + 1
Cells(x, "A").Value = y
x = x + mStep
NoR = NoR - 1
Loop Until NoR = 0

End Sub```

Using the code is done by right-clicking your sheets tab and select "View code". Paste the code in the big white field that pops up.

Best regards,
