Why are you unable to do so? What happens? We need a bit more information. You can copy/paste fields onto a layout with tabs. You must place the object within the tab borders for it to work and not 'bleed' onto all tabs from the layout.
I just cannot copy and paste the fields in the tabs created. Whenever I click on the new tab created, it does not direct me to the tab page (as shown in the filemaker tutorial) and therefore I do not see a blank page where I can copy and paste the required fields.
