Not enough Depth of Field (DOF) is a common problem. You need to use a smaller aperture (larger F#) to increase the DOF. Depending on the available ambient light, you may not be able to stop down the lens far enough. In this case, an external light source will be needed, be it a flash unit or studio lighting. How much DOF you have at a given aperture is also influenced by the focal length of the lens you are using & the distance to your subject...Here's a link to a good online DOF calculator...Bookmark the site as you will find it very useful...
