I'm only a newbie myself, so you may want to take my advice accordingly, but it sounds as though you want to be using a portal to display a list of records under your tab. Whilst you wait for someone better than I to answer your question fully, you might want to take a look at chapter 4 of the user guide or lesson 11 of the user tutorial
Winston may call himself a "newbie" but I agree with his advice. Portals are an extremely useful tool to use in FileMaker and it sounds like exactly the correct approach for listing multiple records inside a tab control. If you encounter specific questions when you try to set that up, feel free to post back here with those questions.
