If cell is updated, write cell value and timestamp in next blank row - excel

Question

I'm trying to update a column with timestamp and another column with updates (which got from a specific cell).
Desired behaviour:
A2 has xy written to it. That change triggers a macro, which puts timestamp in C column at row 2 and the update in D column row 2.
If new update is made in A2: If C2 is not empty, jump to C3 and put timestamp and put update on D3 and so on.
Unfortunately, it puts the first update timestamp and the update to the columns, but if I update again, it doesn't jump and put update there.
Error message and Excel macro
Excel sheet which I try to update.
Private Sub Worksheet_Change(ByVal Target As Range)
Dim xCellColumn As Integer
Dim xCellRow As Integer
Dim xTimeColumn As Integer
Dim xTimeRow As Integer
Dim xUpdateColumn As Integer
Dim xUpdateRow As Integer
Dim xRow, xCol As Integer
xCellColumn = 2
xCellRow = 10
xTimeColumn = 6
xTimeRow = 2
xUpdateColumn = 7
xUpdateRow = 2
i = 2
xCol = Target.Column
xRow = Target.Row
If Target.Text <> "" Then
If xCol = xCellColumn Then
If xRow = xCellRow Then
Do While Range("Munka1").Cells(i, xTimeColumn).Value <> ""
i = i + 1
Loop
Cells(i, xTimeColumn) = Now()
Cells(i, xUpdateColumn) = Target.Value
End If
End If
End If
End Sub

Please try this:
Private Sub Worksheet_Change(ByVal Target As Range)
Dim xCellColumn As Long
Dim xCellRow As Long
Dim xTimeColumn As Long
Dim xUpdateColumn As Long
Dim SupervisedArea As Range
Dim i As Integer
xCellColumn = 2
xCellRow = 10
xTimeColumn = 6
xUpdateColumn = 7
If Target.Text <> "" Then
' If any changed value in the whole column should generate a new data pair:
'Set SupervisedArea = Intersect(Target, Me.Columns(xCellColumn))
' If only one cell should be supervised:
Set SupervisedArea = Intersect(Target, Me.Cells(xCellRow, xCellColumn))
If Not SupervisedArea Is Nothing Then
i = 2
Do While Me.Cells(i, xTimeColumn).Value <> ""
i = i + 1
Loop
Application.EnableEvents = False
Me.Cells(i, xTimeColumn) = Now()
Me.Cells(i, xUpdateColumn) = Target.Value
Application.EnableEvents = True
End If
End If
End Sub
