BrockawayBaby, a semicolon should NOT be used, as there not a list. There are only two items. Even if there was a list, there would not be a semicolon before "respectively" anyway. "Respectively" is a comment on the order of "18" and "200," not part of the items. Your solution is grammatically incorrect.
Comma before “respectively”?
I'll bite.
