These questions you are posting now are very similar to the ones you posted yesterday around 11:00 am
I answered several of them for you then.
You did not reply to any of my posts, so I have no indication that you even looked at them.

Post your answers and I will check them.
They only require about 3 or 4 steps, so it should be no great effort to do so.
