thats not changed whats happening I'm afraid... on the insert or update page, the 'error' Invalid format.Please enter a value. is showing regardless of whether or not there is any content in the field. Also, on the results page, if I have entered 15 Nov 2010 on an insert or update page, the date showing in the results page is: 30 Nov -0001 (and then subsequently showing that in the update page)
