@jertel Hello, can you give me some advice?

[jertel]

1. You can't mix indexed placeholders {1} with empty placeholders {} in the same formatted string. Try switching all your placeholders to indexed.
2. You have a malformed URL: http://http://
3. If after fixing the above and you still have errors, start with a simple URL with no variable substitutions, and work your way up to more complex variations of the URL so you can isolate where the problem is.

Thank you very much, I will try.
