I had to calendar's in one form and things worked well. I changed one field to a hidden field containing the current date using php. The hidden field works properly but now the date picker will not display the year just 3/15/yyyy.

Please help!?

I had the same problem and the only way I could get it to work was to use a 2 digit year instead of 4 digits.

Use dd/mm/y (single y). 4 digit year then shows.
