I am using English UK as my site Language and have disabled all other languages.
When I select a date using the calendar pop-up, the data displays in the form field in English UK format (i.e. dd/mm/yyyy). However, if I pass the result to a query string it displays in English US format (i.e. mm/dd/yyyy). The result does not display in the results sheet if dd in the original selection is greater than 12.
