Add a Subform?

[justdoit]

How can I assign a subform to a form?

An example: I have a form company, and would like to create a subform employee. I have created both forms. How do I connect the whole? That only the coworkers of the respective company are indicated.

I've already found this post. But where I do not know how I give an ID when saving?
