Compare 2 columns find missing data

I want to compare two columns and paste the info from Column E that is missing from Column A into Column B.
I tried VLookup but still new at functions, and scripts. Also not sure if it is better to use function or script?Attached is a file
Thanks

Hi
I do not think I have this working properly I am getting results that are the same on both columns.

Thanks

As an option

Sub find_events()
Dim c2 As Range, c As Range, LR As Long

    Application.ScreenUpdating = 0
    Application.EnableEvents = 0
With Sheets("Sheet1")
    LR = .Cells.Find("*", , , , xlByRows, xlPrevious).Row
    For Each c In .Range("E2:E" & LR)
        If Trim(c.Value) <> vbNullString Then
            Set c2 = Sheets("sheet1").Columns(1).Find(c.Value, , , 1)
            If c2 Is Nothing Then
                   Range(c.Address).Offset(, -3) = c.Offset(, 0)
            End If
        End If
    Next
End With
    Application.ScreenUpdating = 1
    Application.EnableEvents = 1
End Sub

That worked great! Thank You
