Go to next slide only when the last animation is completed

You might try disabling the Next button by using a trigger to Set State of Next to disabled on timeline start, then back to Normal state on timeline end

Hi Brian,

Thanks for your reply.

Any chance you have an example to show me how to do it?

Hi Alexina! Here are the two triggers you'll need:

For the second trigger, the Object is the item on the slide that animates last, and the Animation is the final animation it performs. 

I hope that's helpful!
