Hello, I created an add in with a userform, I want to create a button that
opens the userform when clicked, in order to doing so I have until now in
my
add in workbook:

Private Sub Workbook_AddinInstall()
Application.CommandBars("Formatting").Controls.Add
Type:=msoControlButton,
ID:=2950, Befo=13
End Sub

but I do not know how to assign the macro to the button; the macro writen
