I read it through, figured out the right answer, then parsed visually against what was there and based on what the right answer was, I "thought" I selected the right answer. Turned out it was the wrong one.
What I saw was that the mdy works for all the dates but only works for the first date (cast as datetime) on the dmy. That made it all worth the struggle.

To Steve - you have absolutely the coolest way to read, preview, edit and complete replies on any site I've seen. Can't thank you enough for this great site even though it "occasionally" hurts a bit! I also like that I can whine and get points for it! Kudos.
