The most certain path to "that level" takes you on a course which...
- involves YOU making a serious effort to study the advice you've already been given...
- and involves YOU reading -- carefully, with an eye to understanding! -- the references you've been given: i.e., put on your learning cap, instead of pursuing the 'spoon feed me" approach.
Questions containing the words "doesn't work" (or their moral equivalent) will usually get a downvote from me unless accompanied by:
- code
- verbatim error and/or warning messages
- a coherent explanation of what "doesn't work actually means.
