Created attachment 48546 [details] preview xls file I tried to figure out what the problem is, i think it's in the named cells. reconstruction cell A1 1.5 (given the name euro) cell A2 23.98213 (just a number) cell A3 49.023 (just a number) cell B5 formula: =ROUND(A3+A2/euro,2) --> result 65.01 when I save this file as .ods everything is fine. when I save this file as .xls the formula in cell B5 changed in: =ROUND(#NAME?+A3/A2,2) and give Err:520. when I save the .xls file again the formula disappear and cell B5 gives #N/A
