Hi there,
SO, Those don’t look like the first three lines of the compiler output, ???
more like the errors?
and you failed on the code tags portion 
its at the top of the edit page header between the ""quotes and the UPLoad…
“</>” 
that one, put your stuff in those, for maximum results.

Your close , try again.

This demo ,
uses the LM20A but same libs , so check out the code attached to the posts… Should show you something you are missing? Or Post your code using the code tags above and we can look. 
or this one ,
