sammenkædning af to tabeller, tager for mange poster med...

Prøv evt. i din SELECT sætning at skrive DISTINCT xxxx så burde den fjerne dubletter..

you should normalise your db and then you wouldnt have this problem

If your getting duplicates then it is more than likley because you are selecting fields which are not the same in all records. Try selecting only the telephone number and fax and then right click in the area where the tables are and set the Unique Values property to YES.
