Go to your Layout No 2 and go into layout mode (Ctrl +L). From the Insert Menu choose the first option 'Insert Field'. You will then see the list of all fields already created for the Table that that layout is based on. You can choose any of them to add to the layout. Repeat as necessary. You can also use the 'Add field' button from the toolbar.
You only create fields once. You can then use and re-use them in (basically) any combination on layouts.
What version of Filemaker are you using?
In 'Manage -> Database' how many tables do you see listed? In recent version of Filemaker you will see tabs for 'Tables', 'Fields', and 'Relationships'. Check the 'Tables' tab. If you have more than one table then when you are in Layout Mode you will see fields that are in the table that the layout is based upon.
