Hi Lokiys, thanks for your comment, the forum partner helped me and it works fine with the counter.
What I want from the list is to always visit the 10 urls.
When I finish visiting the last one I start again.
For this the loop counter system works well for me.
That part I have solved, now what I want is that from a list of proxies that I have added take the 1st proxy and visit the 10 urls, then take the 2nd proxy and visit the 10 urls so all the time until they finish the proxies.
I attach the project, but the doubt I have is how to integrate now the function of proxies to work
