I have used the following code from "Microsoft Office Automation with Visual Foxpro" by Tamar Granor but I can't it to work

loTempWorkBook = CREATEOBJECT("Excel.Application")
loTempWorkBook.Workbooks.Open("C:\Dev\Questback\Data\Invicta\Repairs(REP)\"+DTOS(DATE()-1)+"RSLSummary.xls")
loTempWorkBook.Visible = .T.
loMTWorkBook = CREATEOBJECT("Excel.Application")
loMTWorkBook.Workbooks.Open("C:\Dev\Questback\Data\Invicta\Repairs(REP)\"+DTOS(DATE()-1)+"RepairURL.xls")
loMTWorkBook.Visible = .T.

loTempWorkBook.Worksheets(1).Move(loMTWorkBook.ActiveSheet)    && Error on this line 

loMTWorkBook.SaveAs = ("C:\Dev\Questback\Data\Invicta\Repairs(REP)\"+DTOS(DATE()-1)+"RepairURL.xls")
RELEASE loTempWorkBook

Error Message:

OLE IDespatch exception code 0 from Microsoft Office Excel:
Unable to get the move property of the Worksheet class

Is there something missing in the move syntax? Can any one help? Is there another way to do this?
