[AccessD] form - subform problem

Hello Group,


I use the code below to open a (sub)form so that the data of PrProduktgegevens1ID is also present on this (sub)form. I have 10 PrProduktgegevensID fields on the head form. Each PrProduktgegevenID has its on new (sub)form. The headform and all the 10 (sub)forms have the same query as Record Source. But many times when i open the (sub)form, the data of the PrProduktgegevensID isn't placed. Its fields are empty. How is this possible? Can i better also place the recordID of the headform in the stLinkCriteria?
(sorry for the bad explanation of this problem. But i find it difficult to explain the problem in English)

TIA


Pedro Janssen
