Katie Beach this is usually caused by a lens that can either no extend or retract. Check some of the things on here http://camerarepair.blogspot.com/2007/12/fixing-lens-error-on-digital-camera.html and see if that works. If it does not you may have to consider a lens replacement. [[Topic:Nikon Coolpix L840|These guides]] should help you to at least get into your camera and check [https://www.youtube.com/watch?v=j9Ye8XJ_o5c|this video] to see where it may be stuck as well. I do not necessarily support a Dremel tool for the repair ;-)
