Run Macro on multiple worksheets within an excel file

[biyi11]

Hello,

I am trying to create a macro to run on all worksheets within a tab. So far it is only running on one worksheet and it does not work on other. Can someone please assist me. Below is the code I used. Thank you

Dim ws As Worksheet
For Each ws In ActiveWorkbook.Worksheets
If ws.Name <> "Sheet1" Or ws.Name <> "Sheet2" Then
Columns("F:H").Select
Range("H1").Activate
Selection.EntireColumn.Hidden = True
End If

Next ws.Activate
End Sub
