Dim base layer
I know it can be done because I have done it on a few slides...I just can't figure out how to replicate what I did on those slides.
I have a base layer with markers on it. I want the user to view each marker prior to progressing. If they do attempt to progress prior to viewing all of the markers I have a layer that is just a text box that says "Please view all markers before advancing" when the text box appears I want everything on the base layer to be dimmed. I was a able to do it a few weeks ago on a different slide but now I forget what I did.
