Too many array formulas

hi, please find attached a spreadsheet. when i copy cells A5:AO5 and paste those cells in the range A6:AO200 and then save in excel 2003 format i get the too many array formulas refering to other spreadsheets warning. but the range names i have defined are in the same spreadsheet so why do i still get this warning?

any help would be much appreciated.
thanks
