Message box pop up

Question

I need to build a code to give me a pop up message if the value of a cell (Price) is bigger than another cell (Target). If PRICE > TARGET then pop up a window (ideally with sound).

Also if I hit ok i need to register "true" to another cell or if i hit cancel insert to a cell FALSE

My FIRST vba code so please show some understanding, Thanks a lot in advance.

Private Sub CommandButton1_Click()

Sub userinput()

Dim ireply As Integer

If Range("C6").Value > Range("E6").Value Then

ireply = MsgBox(prompt:="Price" & Range("F6").Value & " Reached target. Stop tracking ?", Buttons:=vbYesNoCancel, Title:="Tracking")

If ireply = vbYes Then

Range("B6").Value = "TRUE"

ElseIf ireply = vbNo Then

Range("B6").Value = "FALSE"

End Ifs

If Range("C7").Value > Range("E7") Then

End If

If Range("C8").Value > Range("E8") Then

End If

Exit Sub

End Sub

To make this possible directly when you input data into Excel, you'll need to place this into the sheet module of the sheet that you want it to work on :

Private Sub Worksheet_Change(ByVal Target As Range)
Dim iReply As Integer

If Target.Count > 1 Then Exit Sub

If Application.Intersect(Target, Columns(3)) Is Nothing Then
Else
    If Range("C" & Target.Row).Value > Range("E" & Target.Row).Value Then
        Beep
        iReply = MsgBox("Price" & Range("F" & Target.Row).Value & " Reached target. Stop tracking ?", vbOKCancel + vbCritical, "Tracking")
        If iReply <> vbCancel Then
            Range("B" & Target.Row).Value = "TRUE"
        Else
            Range("B" & Target.Row).Value = "FALSE"
        End If
    Else
    End If
End If

End Sub
