Animations Options Greyed out on Menu
I've viewed the tutorials several times on adding entrance and exit transitions to slides. When I choose a slide or a layer and click on "Animations", the menu items for "Entrance" and "Exit" are greyed out and not clickable. When I click on the type of transitions I want (fade) and the time (fast) and what I want it to apply to, the transition doesn't activate. So the transitions just won't apply to the screen. Suggestions?
