[excel] Declaring variable workbook / Worksheet vba

I know this might come off as a trivial question, but I can't seem to declare a workbook or a worksheet as a variable in VBA. I have the following code, but I can't figure out what I am doing wrong, it should be straight forward. Normally I don't have any problems declaring variables such as Dim i As Integer etc.

sub kl() 

    Dim wb As Workbook
    Dim ws As Worksheet

    Set wb = ActiveWorkbook
    Set ws = Sheet("name")

    wb.ws.Select

End Sub

When I run the above code, I receive a type missmatch error.

Use Sheets rather than Sheet and activate them sequentially:

Sub kl()
    Dim wb As Workbook
    Dim ws As Worksheet
    Set wb = ActiveWorkbook
    Set ws = Sheets("Sheet1")
    wb.Activate
    ws.Select
End Sub
