I have a ppt that has a master slide that I want to use as an introductory slide. Then when I click the second time I want the presentation to advance to the second slide and start the actual presentation.

In that master slide I have 15 items that I have animation set. I want to repeat these animations until I am ready for the actual presentation to start. I need it to pause for 5 seconds at the end of the 15th animation before it starts with the 1st animation again. Thanks in advance.
