Hi @ceit, welcome to our community!

English:  
If you look at the error it says that the file `Turn.srv` cannot be found so you have to verify the path:

- Check if the file `Turn.srv` exists in the directory `services_quiz_srv` within your workspace (for example, `src/custom_interfaces/services_quiz_srv`).
- Ensure that the path to `Turn.srv` is correct and that it’s in the expected location relative to your `CMakeLists.txt` file.
- If you did not make `Turn.srv` file you might skip one of the steps, so verify you follow all the notebook steps.

Spanish:  
Si observas el error, dice que no puede encontrar el archivo `Turn.srv`, por lo que debes verificar el path:

- Verifica que el archivo `Turn.srv` exista en el directorio `services_quiz_srv` dentro de tu espacio de trabajo (por ejemplo, `src/custom_interfaces/services_quiz_srv`).
- Asegúrate de que la ruta a `Turn.srv` sea correcta y de que esté en la ubicación esperada en relación con tu archivo `CMakeLists.txt`.
- Si no creaste el archivo `Turn.srv`, es posible que te hayas saltado uno de los pasos, así que verifica que hayas seguido todos los pasos del notebook.
