How to run same code (VBA) for other sheet of a work book?

[maftoun]

Greetings,

This is my VBA for 1st sheet of my workbook,
It is in the Module 1

Public Sub MyMacro()
    Sheets("a").Select
    Tempcell = 0
    For Each Bcell In Range("j14:j26")
        If (Bcell = 0) Then
            Range("j28") = Tempcell
        End If
        If Not (Bcell = 0) Then
            Tempcell = Bcell
        End If
    Next Bcell
    Sheets("a").Select
    Tempcell = 0
    For Each Bcell In Range("u14:u25")
        If (Bcell = 0) Then
            Range("u28") = Tempcell
        End If
        If Not (Bcell = 0) Then
            Tempcell = Bcell
        End If
    Next Bcell

    
End Sub

Also I have

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Run "MyMacro"
End Sub

In worksheet (a) Selection change of Excel Object.

My question is how I can to "RUN" same VBA for other 7 sheets (b - h) of same workbook ?

Thanks for your help
