### PS

Please dont post pictures - they cannot be searched (by future readers with similar issues) and they are hard to read - PLEASE post as text - and - In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote `````)

````auto
``` 
   code goes here 
```
