Delaying Next button
I have a slide with several layers. I don't want anyone to click Next by mistake and miss some of the layers. Does anyone know how I can delay the appearance of the Next button until all layers have been visited?
I thought about turning off the Next in slide properties and then adding a manual Next button at the end of the last layer...which would go to the next slide. But, I need to direct them back to the slide (from the layers) and then move onto the next slide.
