Adding two cells error usng VBA for excel

I am trying to write my first code ever in excel VBA for Mac. All I want to do is add two numbers. Sounds Hard, Right? I keep getting this error Compile Error: invalid use of property. Then a debugger window opens with the first line highlighted.

     Sub abbas()
    'adds two numbers
    'from e2 and e3 and puts the result in e4
    Sheets("SHEET 1").Select
    Range("e2").Select
    A = ActiveCell.Value
    Range("e3").Select
    B = ActiveCell.Value
    Range("e4").Select
    ActiveCell.Value = A + B
    Range ("e5")
    End Sub
