Hi Enrik, after 3 weeks of hard wok, now i'm trying to resolve the problem. Some questions:
That is the table:

The number of rows of the table could be different, and the link at the right open a page in which i can download the file.
1. For extract the data from a table which kind of istance ? I use "obtain details of element of a web page", but i can choose "Own Text", "Source Link", "Href" etc...... Which is the right value ? Own text give me an error.
2. And after ? i have to make a loop to push every element on the right of the table (in the red circle) to open the page and extract the file....
I'm very sorry, but it's difficult for me to move on at this point.
