search: /rep/results.asp
go to line 77 (search for start_date) and modify the line to match your local date format.
do the same for end_date.
reports:/admin/viewreports.asp
go to line 44 (search for start_date) and do the same as you did for the search.
This fixes the issue where certain search and reports fail to return a result because the date is interpreted wrong by sql as it uses the date format supplied by your sql server. Not sure if this affects access but I would assume it's the same.
The alternative is to change the date format on the sql server but it's a bit much for muchness.
