Sub Macro1()

Application.Run Range("AUTOSAVE.XLA!mcs02.OnTime")
Range("E10").Select
ActiveCell.FormulaR1C1 = "save this file as the value in this cell"
ChDir "C:\Documents and Settings\df78700\Desktop"
ActiveWorkbook.SaveAs Filename:= _
"C:\Documents and Settings\df78700\Desktop\save this file as the
value in this cell.xls" _
, FileFormat:=xlNormal, Password:="", WriteResPassword:="", _
ReadOnlyRecommended:=False, CreateBackup:=False
End Sub
