Please ask as many questions as you like, that’s what the forum is for 
The bracket is not quite correct in this case, it should be:
access:conditional=yes @ (Mo-Fr 17:00-07:00; Sa-Su)
But in this case, however, Monday morning will always be missing, so we have to specify the individual time ranges individually so that each day really works.
access:conditional=yes @ (Mo-Fr 00:00-07:00,17:00-24:00; Sa-Su 00:00-24:00)
