Removing formulas in all sheets by Paste/Special

Hi,

I have written a short piece of code based on some other posts and for some reason it doesn't work and it's driving me mad. The task seems to be very easy - I'm trying to get rid of some formulas in all worksheets and keep the actual values only. The part that is failing is the following: ws.Range("A1:P31").Select

Sub CopyPasteSpecialAllSheets()
    Dim ws As Worksheet
    Application.ScreenUpdating = False
    
    For Each ws In Worksheets
    
    ws.Range("A1:P31").Select
    Selection.Copy
    Selection.PasteSpecial Paste:=xlPasteValues
    Application.CutCopyMode = False

    Next ws
End Sub

When I take out "ws" from ws.Range("A1:P31").Select then the code works fine, but it doesn't loop through all worksheets - it executes 78 times the code on the active worksheet....

Any ideas on how to fix it and why this happens?
