Hi Gorka, could you describe a bit more, on the setting of page before or after adding? Do you use a string or numeric to set the parameter, and if i want the datas to be set to say, workbook (project.xls), sheet 2, how would you set it? I tried to use index, rather than add method, and when i set the index to 0, the datas will be at sheet 1, and for other index numbers, there would be an error of code 1.
