Thanks, but I always get an error message. It is probably something stupid but as long I do not know exactly waht, I will stay .... stupid. Please see attachment.
Apologies, cancel that last sentence - I hadn't looked at the updated screenshot that you updated.
It may well be worth altering your field name in the query to identically match the field name in the table. At the moment it is quoted as 'man_naam' when the actual field name in the table is 'Man_Naam'.
