Hi! I have a seach form to let website visitors 'filter' articles / seblod content. This works fine, except for the checkbox fields. I have a field with 4 option. Each can be checked. When I use the form to filter on one of these options it works fine. When I check te first and second, also fine, 1st 2nd and 3th: Works. Check all 4: Works fine! But when I select 1st and 3th checkbox, the result are wrong! Or 1st and 4th. Also wrong.
Any clues why this is happening and how I can solve this?
Thanks!
