Hello Naomi and Christof

I solve the problem with the messagebox command send by Naomi (messagebox(sys(2023)), and the problem is that the path of my excel file use path with long file name
and VFP don´t like that, also i save the same file on my C:, and now they work.

Many thanks for both, because always with your kindly replies i learn other useful technique to debbug my coding.

Best regards and thanks you
