Yes. I can't get the test file correct. I have asked for help on the forums and received none today. I am hoping that an admin on here could give me a little help. I am only 16 and this is a steep learning curve for me as I have never used git or even github up until several days ago. The link to my forum post with full details is here: [Forum Post.]( https://duck.co/forum/thread/6553/test-file-development-help)
