I believe you are having the same problem here.
The sheet must be active before you can select a range on it.
Also, don’t omit the sheet name qualifier:
Sheets("BxWsn Simulation").Select
Sheets("BxWsn Simulation").Range("Result").Select
Or,
With Sheets("BxWsn Simulation")
.Select
.Range("Result").Select
End WIth
which is the same.
