If I select Days 11 & 12, yourCollection will have those days added to the collection. But, if I re-open the calendar and want to change the days selected to Days 10 & 11, in my collection I have 10, 11, 11, 12 days (4 days). Instead of 10 and 11. How do I get 10 & 11 without clearing the collection all together?
It seems to me that the issue is when I deselect the calendar day (no longer high-lighted) the _selectionStart and the _selectionEnd entry is still the last entry selected, they do not go back to blank. Any thoughts on how to do that? I guess it has to do with my count???
