trying to get a reference to a named range in a different (open) worksheet:

this result in an error (9):
Workbooks("Book1.xls").Worksheets("Sheet1").Range( "RateDesigner")


when i type the final dot after: workbooks("Book1.xls").
i get a drop-down list that includes: worksheets

when i type the final dot after : worksheets().
i get a drop-down list; but, it does not include: range

when i type the final dot after worksheets("Sheet1").
i do not get even a drop-down list


suggestion ?
