Though your problem is not so clear as with the language, I think this can be soloved as follows.

Do you mean to create an automatic Master-Detail relationship with two blocks? If yes, then don't worry. It's Built in Forms. You don't have to write a single line of script for that. Create the master block first. Then Create a detail block.
Note. There should be a primary key in master block and a foreign key in detail block with the same date type.

Then.. if you created the master detail relationships in the table level itself, then, you can build the master detail relationship when you create the detail block. Go to Master/Detail tab and select the master blcok. and press OK. That's all

Sencondly if you didn't create in table level then in master block go to relations and create NEW. then select the MASTER and DETAIL blocks and a name for the RELATION. then in the Join condition, give the condition as MASTER_BLOCK.COLUMN=DETAIL_BLOCK.COLUMN
and press OK.(where MASTER_BLOCK.COLUMN is the primary key in MASTER_BLOCK and DETAIL_BLOCK.COLOUMN is the foreign key to MASTER_BLOCK.COLUMN)
This will create all necessary scripts for the auto populating and validations.

hello and thanks for your answer. I would like a relation between two form modules and not between two blocken.ich have two masks: the parent mask shows all data records of table of name parent(parent_id<pk >, parent_name, parent_vorname). this mask has button name child them the child mask is opened, and it shows data records of another table of name child(child_id, parent_id<sk >, child_name). Relation 1--n between the two tablellen. if the child mask is opened, only the data records may be shown by table the child with clausel: parent_id=parent.last_current_parent:id. if changes the actuelle data records, I it store I it and give that to control to the child mask .this must then be updated and new data records shown. I hope: the problem became clear now.
