Hi all,

Im working on a project where i need multiple VBA codes to be able to run on the one sheet, im not massively excel savvy and ive got the below from other sources. When these codes are on their own they work as intended but when i add them all in they dont work as expected and im a bit stuck. I need the below to be able to work seamlessly as one. In Cell C6 i have a drop down list where i have 5 options to select from, when i select an option i want a message box to appear with information for the user to read, after this in Cell J16 i have a list that allows multiple selections without repetition so i can select several items from the list each separated by a |. From what i have read and researched thus far i know i cant have two Private Sub Worksheet Changes at the same time, ive tried to rename them but to no avail. If any of you kind souls could help on this id be in your debt. Thanks in advance.

VBA Code: 
Private Sub Worksheet_Change(ByVal Destination As Range)
Dim rngDropdown As Range
Dim oldValue As String
Dim newValue As String
Dim DelimiterType As String
DelimiterType = " | "
Dim DelimiterCount As Integer
Dim TargetType As Integer
Dim i As Integer
Dim arr() As String
 
If Destination.Count > 1 Then Exit Sub
On Error Resume Next
 
Set rngDropdown = Cells.SpecialCells(xlCellTypeAllValidation)
On Error GoTo exitError
 
If rngDropdown Is Nothing Then GoTo exitError
 
If Not Destination.Address = "$J$16" Then GoTo exitError
 
TargetType = 0
    TargetType = Destination.Validation.Type
    If TargetType = 3 Then  ' is validation type is "list"
        Application.ScreenUpdating = False
        Application.EnableEvents = False
        newValue = Destination.Value
        Application.Undo
        oldValue = Destination.Value
        Destination.Value = newValue
        If oldValue <> "" Then
            If newValue <> "" Then
                If oldValue = newValue Or oldValue = newValue & Replace(DelimiterType, " ", "") Or oldValue = newValue & DelimiterType Then ' leave the value if there is only one in the list
                    oldValue = Replace(oldValue, DelimiterType, "")
                    oldValue = Replace(oldValue, Replace(DelimiterType, " ", ""), "")

Solution
Hi,
Where you require multiple addresses to run code from your WorkSheet_Change event another option to consider is to break them in to their own codes & call them from the event as required - this should make your codes easier to read & debug.

For example

Place following code in your worksheets code page

Code: 
Private Sub Worksheet_Change(ByVal Target As Range)

    If Target.CountLarge > 1 Then Exit Sub
    
    If Not Intersect(Target, Me.Range("C6,J16")) Is Nothing Then
    
    Select Case Target.Address(0, 0)
        Case "C6"
            CheckHistory Target
        Case "J16"
            DestinationChange Target
        Case Else
            'other addresses as required
        End Select
  End If
  
End Sub

Place following codes in their own STANDARD Modules

Code: 
Sub CheckHistory(ByVal Target As Range)
    Dim m                  As Variant
    Dim strValidation As String
    
    On Error GoTo myerror
    If Target.Validation.Type = xlValidateList Then
        
        strValidation = Target.Validation.Formula1
        
        m = Application.Match(Target.Value, Split(strValidation, ","), 0)
        If Not IsError(m) Then
            MsgBox Target.Value & " - " & Choose(CLng(m), "Check full history And 5&2 rule", "Check full history And 5&2 rule", _
                                                                                           "Check history And exclusions", "Check history And exclusions", _
                                                                                           "Take brief history only"), 48, "Check History"
        End If
    End If
myerror:
    If Err <> 0 Then MsgBox (Error(Err)), 48, "Error"
End Sub

Code:

Codes are untested & you will need to adjust to meet specific project need as required but should give another idea that may help resolve your issue
