hello Paul,
new in the forum,
I ask you to tell me about my mistakes.
I just saw and corrected the problem in my title.
If there is an error you can see, other than that, please inform me.
thank you.

Is it difficult for you to read the forum guide because it is written in English? What is your preferred language? Perhaps there is a forum section for your language where you can get help more easily.
