I would be grateful for assistance.
I'm a newcomer self study student.
I inserted my solution to the Not gate sub-project, but there was that red remark at the bottom of the page
"Chip 1 is not fiound in the working and built in folders".
The truth is that it was'nt really my answer - I figured it out by going throug answers to questions in relation the the gate, from this forum. I do not see consistency between the in and out interface, to the solution.
I would be grateful for an explantion of what the error message means.

Thank you all
Ron
