Sorry for being late in my reply.
Yes, all the tables involved have indexes, but I think that the error is caused by different version of VFP9 libraries. Maybe the setup i used to set the other PC contains an older version of VFP9 dlls. As I told you I don't have the error if the "Fornit" table is not empty, though I never had problems on my PC even using the same database with the same data. It's the only answer i can give to this behaviour.


>>The line with the error is that one :( anyway I realized that I got the error if I have the Fornit table empty.
>>I cannot explain the reason why i get no error from my pc even reading the same data
