Hi,
When you are working on your pages, it is very important, that the a layout is the same on each page for anything that repeats itself on the subsequent pages.. to do this, you must click on the layout tab at the top of the page you are working on. Here you will find the ability to place a grid on your page that is only visible to you in the working stage. You can also place a virticle or horizontal line on your page, which is also movable to your needs to assist you lining up different additions, be it photos, text or other add ons. Once you have things all lined up, click on Edit which is next to File and then on Lock All. This will help you avoid inadvertantly moving things without knowing..You can always unlock individual parts of the page by right clicking on them

Cheers
