I have a form which displays information about a particular record. When I click on my navigation buttons I want to display child records in a listbox which is bound to another table using the field artikey. In the click event I use a set filter:

SELECT article
SKIP -1
cArtikey=article.artikey

SELECT cmscomp
SET FILTER TO Artikey=cArtikey

But when I change records nothing happens in my listbox. Canybody help me please?
