Linking more than one criteria to open form

[Kyriakos]

Hey all. This is what I have to deal with. I have this form with subform. Based on a certain selection on the form the subform opens. And on the subform when I select a value a new subform must pop up. So far so good. Problem appears on the nested subform I get all matching results regardless of the first selection (of the form).

So what I need to do is find a way to relate two matching fields to open form. The wizard prompts you to select just one, but through this I don't get what I want....

Any help? PLEASE!!!!!

Thanks, Kyriakos....
