I am trying to have two reservation calendars side by side, one with allowed dates for 2012 and one for 2013. Since there is no function to block out dates within a year e.g. 4/5 - 5/20 and then 6/23 - 7/20
I have to resort to using two separate inputs. However, the second calendar always reverts back to the dates of the first one and now after 8 or 9 unsuccessful attempts to load the changes it is not even accepting a manual date change anymore. This is super frustrating. Anybody out there who can help me solve this?

Sounds like you're using the same file name for both calendars? Got a link so we can take a look?

I re-started the program and was able to change the dates.
I found out that only if I change the dates in the visual calendar my choices will stick. If I enter
the dates manually e.g. 3/12/12 it will revert back to the previous settings.
I named both calendars differently btw.

Programmers: It would really be nice if you find a way to exclude dates in the calendar within the same year or even into the next year. We close for a few weeks during the Summer and it would be nice to be able to block those dates from the choices. Just an idea, Others might find this useful too
