eddyskrbo i am no genius when it comes to this box, but i had same thing. I ignored the Add Line bit at the top (hit return a few times to create space) , and just pasted my line into the top of where all the text about types of cams are , then hit save, waited a few secs. Then went back a page, and hit edit ccam again to check it had, changed , it had. So ignore the obvious place to type in c-line, and paste it in the window below.
