Hi Nancy,
Make sure you have a white background block on the A-layer, that covers the entire page area, and the length of your vertical. Make sure to group all your elements, otherwise some might disappear behind the background. Also I assume that since you are doing it without a B-layer that you are designing for one, specific orientation. So make sure that you set the orientation of your vertical to the wanted orientation (landscape or portrait).
Best regards
