What is wrong with this code:
If Not Sheets("Harrison 1") Is Nothing Then
Sheets("Harrison 1").Select
Range("A3:C3").Select
Selection.Copy
Windows("DAY AHEAD LMP SHEET.xls").Activate
Range("B4").Select
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone,
SkipBlanks _
:=False, Transpose:=False
Windows("Day Ahead Obligation.xls").Activate
Range("B6:C29").Select
Application.CutCopyMode = False
Selection.Copy
Windows("DAY AHEAD LMP SHEET.xls").Activate
Range("C7").Select
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone,
SkipBlanks _
:=False, Transpose:=False
Else
Windows("DAY AHEAD LMP SHEET.xls").Activate
Range("C7:D30").Select
Selection.ClearContents
End If

If I run this on a spreadsheet where there is no "Harrison 1" sheet, I
receive a runtime error 9 "subscript out of range" on the "If Not
Sheets("Harrison 1") Is Nothing Then" statement.
