Hi folks,
Please can someone help me with the following:

(I am using PPT2010)

I have a slide showing 4 different text blocks on a touchscreen device.

I would like to be able to tap on any of the 4 blocks and have a pre-determined videofile associated with that text played automatically in full screen. When the video has finished I want to have the slide with the 4 text blocks back on the screen.

Kind of a kiosk effect.

Can any of you help me?

Thanks in advance for the help.
