If you've already got fields on the form before adding the tab pages then the fields will still be sitting on the detail section of the form. What you need to do is highlight the fields you want for the first tab page, copy and delete them, click the page you want them on and then paste them. Note that if you've got any code attached to the fields you'll need to attach it back to the field's event procedure.
If your form is blank, it's the same really, as you add the fields for that tab control, make sure the tab control is selected first, if not the field will sit on the detail section of the form.
Does that help?
