Question

Worksheet A has ranges of data that are collected from Worksheet B. Worksheet A has a macro that calculates if the data is above a value then calls an email module to email selected users.

When the data is manually input on Worksheet A the Macro works, however when data is pulled from Worksheet B it doesn’t fire.

I’m not sure what I need to change in my VBA code.

Private Sub Worksheet_Change(ByVal Target As Range)
    Call MailAlert(Target, "B5:M5", 4) 
    Call MailAlert(Target, "B8:M8", 7) 
    Call MailAlert(Target, "B11:M11", 6)
    Call MailAlert(Target, "B14:M14", 2) 
    Call MailAlert(Target, "B17:M17", 4) 
    Call MailAlert(Target, "B20:M20", 1) 
    Call MailAlert(Target, "B23:M23", 3) 
    Call MailAlert(Target, "B26:M26", 1) 
    Call MailAlert(Target, "B29:M29", 5) 
    Call MailAlert(Target, "B32:M32", 1) 
    Call MailAlert(Target, "B35:M35", 7) 
    Call MailAlert(Target, "B38:M38", 20) 
    Call MailAlert(Target, "B41:M41", 0) 
End Sub

Private Sub MailAlert(ByVal Target As Range, ByVal Address As String, ByVal Value As Integer)
    If Target.Cells.Count > 1 Then Exit Sub
    If Not Application.Intersect(Range(Address), Target) Is Nothing Then
        If IsNumeric(Target.Value) And Target.Value > Value Then
        Call Mail_small_Text_Outlook
        End If
        Application.EnableEvents = True
    End If
End Sub

Answer 1

To capture the changes by a formula you have to use the Worksheet_Calculate() event. To understand how it works, let’s take an example.

1. Create a New Workbook.
2. In Sheet1 Cell A1, put this formula =Sheet2!A1+1

Now In a module paste this code

Public PrevVal As Variant

Paste this in the Sheet Code area

Private Sub Worksheet_Calculate()
    If Range("A1").Value <> PrevVal Then
        MsgBox "Value Changed"
        PrevVal = Range("A1").Value
    End If
End Sub

And lastly in the ThisWorkbook Code area paste this code

Private Sub Workbook_Open()
    PrevVal = Sheet1.Range("A1").Value
End Sub

Close and Save the workbook and reopen it. Now Make any change to the cell A1 of Sheet2. You will notice that you will get the message box MsgBox "Value Changed"
