Animation across multiple slides - please help

[jpscience]

Hi,



Is it possible to have an animation in PowerPoint 2010 which runs over multiple slides? I can place an animation in the slide master, but this just resets when you go to the next slide.

It is possible to have sound playing over several slides, but I can’t find a way of doing this for a custom animation.

What I’d like to do is have a countdown timer running over the whole presentation.

Thanks for your help.

Best wishes,
