Axolot Data

I wrote the following code: XLS[0].AsFormula[2+3,Row]:= 'LOOKUP(HojaLecturas!'+A3+',Costos!$A$2:$B$244)'; when I open the sheet with Excel appear: #¿NOMBRE? So, changing nothing, I click the Fx button on the cell , close the window and the function appear correctly What am I missing in my code? Than...

Does XLSReadWriteII 5 work with Delphi 6 ?
