Prevent EventChange Sub running unexpectedly - excel

Question

Advice would be gratefully appreciated. I am developing a spreadsheet using Excel 2016/Windows.
I have written 4 eventchange subroutines and all work well. The VBA Code for a worksheet checks for 4 events. Event 1, 2 and 3 enter today's date in a cell if data is entered in another cell (code not included below)
Code for EventChange works fine, but sometimes works when not expected to!
EventChange4 moves a value from one cell to another if another cell contains the text in Column J is "THIS Month – Payment Due" or "Issued But Not Paid. The second part of this eventchange4 moves a zero value to 2 cells if the data in column j contains text "not going ahead"
I am new to VBA. The problem is that eventchange4 runs for no apparent reason, e.g. copying a cell value in column H down to another cell in column h. How can I modify the code such that that eventchange4 only runs when the data in Column J Changes??? All advice gratefully accepted!!!!
Private Sub Worksheet_Change(ByVal Target As Range)
Call EventChange_1(Target)
Call EventChange_2(Target)
Call EventChange_3(Target)
Call EventChange_4(Target)
End Sub
Sub EventChange_1(ByVal Target As Range)
'Update on 11/11/2019 -If data changes in column L, insert
'today's date into column M
End Sub
Sub EventChange_2(ByVal Target As Range)
'Update on 15/01/2020 -If data changes in column P, insert today's date
'into next Column Q
End Sub
Sub EventChange_3(ByVal Target As Range)
'Update on 15/01/2020 -If data changes in column R, insert today's date
'into next Column S
End Sub
Sub EventChange_4(ByVal Target As Range)
On Error Resume Next
Application.EnableEvents = False
' this works !
If Target.Column = 10 And (Target.Value = "THIS Month – Payment Due" Or Target.Value = "Issued But Not Paid") Then
Range("K" & Target.Row).Value = Range("I" & Target.Row).Value
Range("I" & Target.Row).Clear
MsgBox "Moved Commission Due to Month Paid"
End If
If Target.Column = 10 And (Target.Value = "Not Going Ahead") Then
Range("I" & Target.Row).Value = 0
Range("K" & Target.Row).Value = 0
MsgBox "Moved ZERO to Initial Commisson and Month Paid"
End If
Application.EnableEvents = True
End Sub

Ideally you should update your code so it can properly handle a Target range which is not just a single cell:
Sub EventChange_4(ByVal Target As Range)
Dim rng As Range, c As Range, v
'any part of Target in Column J?
Set rng = Application.Intersect(Target, Me.Columns(10))
If Not rng Is Nothing Then
'have some cells to process...
On Error GoTo haveError
Application.EnableEvents = False
'process each affected cell in Col J
For Each c In rng.Cells
v = c.Value
If v = "THIS Month – Payment Due" Or v = "Issued But Not Paid" Then
Range("K" & c.Row).Value = Range("I" & c.Row).Value
Range("I" & c.Row).Clear
MsgBox "Moved Commission Due to Month Paid"
End If
If v = "Not Going Ahead" Then
Range("I" & c.Row).Value = 0
Range("K" & c.Row).Value = 0
MsgBox "Moved ZERO to Initial Commisson and Month Paid"
End If
Next c
End If
haveError:
Application.EnableEvents = True
End Sub
NOTE: this is assumed to be in the relevant worksheet code module - otherwise you should qualify the Range() calls with a specific worksheet reference.
All your "change" handlers should follow a similar pattern.

Tim apologies. I am new to this and was anxious to get a solution. Thank you for your response. Advice Noted. T
When I attempt to insert or delete a row in the spreadsheet, the VBA code identifies a worksheet event and attempts to run the code. The spreadsheet crashes. I have attempted to add code that will prevent this by checking at the beginning of the module if a row has been inserted or deleted before the other worksheet change event if statements are checked
Thank you
