Just for future info I had the same thing happen to me in January. I had vacation the last week and did not want to use it and basically stash it away for sell back at the end of the year. NO GO. Futures built me a vto month using a credit of 42 hours and then added a trip to make a full month. Also you cannot go into makeup vacation with the same intent of selling it back at the end of the year. Final analysis is that if you want to sell back a week or two of vacation each year you must bid around those weeks to have off. Usually this means domestic unless your real senior.
