Good morning everyone,

I apologize for the delay on this topic, without much time available

I didn't understand everything you wanted, but here is an example with some parts that I understood

I attached a file

 

Option Explicit

Dim nextStepProgram As Boolean

Private Sub Worksheet_Change(ByVal Target As Range)

Dim intRowCount As Integer

If nextStepProgram = False Then
     nextStepProgram = True
     intRowCount = CheckNumb
     Call Update_DataValidation(intRowCount)
     nextStepProgram = False
End If

Call getAllCellsWithValidation

End Sub

Private Function CheckNumb() As Integer

Dim i As Integer
Dim nextStep As Boolean

i = 1
nextStep = True

While nextStep = True
     If Cells(i, 1) <> "" Then
         i = i + 1
     Else
         nextStep = False
     End If
Wend

CheckNumb = i - 1

End Function
