Excel VBA looping through multiple worksheets

Question

VBA beginner here, I've got a little problem with program I'm working on.

I need to copy data from last cell in column B from first worksheet and paste it into column A in another worksheet xws, and repeate this operation for five other worksheets with data.

Here's the code, it doesn't work the way it should:

Sub exercise()

    Dim ws As Worksheet
    Dim rng As Range
    'Finding last row in column B
    Set rng = Range("B" & Rows.Count).End(xlUp)

    For Each ws In ActiveWorkbook.Worksheets
        'Don't copy data from xws worksheet
        If ws.Name <> "xws" Then
            'Storing first copied data in A1
            If IsEmpty(Sheets("xws").[A1]) Then
                rng.Copy Sheets("xws").Range("A" & Rows.Count).End(xlUp)
            'Storing next copied data below previously filled cell
            Else
                rng.Copy Sheets("xws").Range("A" & Rows.Count).End(xlUp).Offset(1, 0)
            End If
        End If
    Next ws
End Sub

There is a problem with ws. referring, but whenever I put it before rng in if statements or before range (set rng = ...) I get errors.

Thanks in advance for any pointers.

You should be declaring rng for each ws inside the loop, like:

Sub exercise()
    Dim ws As Worksheet
    Dim rng As Range

    For Each ws In ActiveWorkbook.Worksheets
        'Finding last row in column B
        Set rng = ws.Range("B" & ws.Rows.Count).End(xlUp) '<~~ Moved inside the loop
        'Don't copy data from xws worksheet
        If ws.Name <> "xws" Then
            'Storing first copied data in A1
            If IsEmpty(Sheets("xws").[A1]) Then
                rng.Copy Sheets("xws").Range("A" & Rows.Count).End(xlUp)
            'Storing next copied data below previously filled cell
            Else
                rng.Copy Sheets("xws").Range("A" & Rows.Count).End(xlUp).Offset(1, 0)
            End If
        End If
    Next ws
End Sub

As your code is now, rng will be pointing to the ActiveSheet at the time you run the macro, and your code will then copy the same cell on each iteration of the code.
