Narrative:

Did not reset altimeters during climb through FL180. We were given several amendments to our next altitude assignments at approximately FL180, and we missed the changeover. We received a TCASII TA simultaneously with a query from ATC to check altitude. We had visually acquired other aircraft and were overtaking along same route. No evasive actions were necessary or taken.
