Subroutine loop -- Stops after first, active sheet

Trying to loop a subroutine through x worksheets, where x < n and n is the total number of worksheets in ActiveWorkbook. Worksheets in X have unique names (character strings). My sub keeps running on the first sheet in the book and no other. Help?

Sub countpiece()
Dim ws As Worksheet
Dim i As Long, j As Long, k As Long, g As Long, h As Long

i = 0
j = 0
k = 0
g = 0
h = 0

Application.EnableCancelKey = xlDisabled

For Each Worksheet In ActiveWorkbook.Worksheets
    
    Select Case Worksheet.Name
        
        Case "abur", ... (more sheet names here, not including the first, active sheet's name)(code following sheet names contains instructions for operations. Condition/repeat structure ends like this:)

            Case Else

End Select

Next Worksheet

End Sub
