workbook error - please help

[PBcorn]

why does

workbooks("book1.xls").close

(book1 is open in the current instance of excel, code is in book2)

generates a subscript out of range error - why? i have tried specifying
savechanges = .... but this is an optional argument i believe

Sub closeit()
Workbooks("Book1").Saved = True
Workbooks("Book1").Close
End Sub
