Can I get my slides to loop on their own?

Is there a way that I can get my slides to loop on their own? Like if i want to have some announcements looping while people are getting seating before service... without having to click on it? Thanks in advance!

Yes!  Edit the cue you would like to use for your looping announcements.  Under the foreground options, there is an "Auto Advance" panel.  You can set the loop settings there.

I'm trying to loop a section that has Power Point slides in it.  For some reason the "Auto Advance" panel says "Cue auto advance options not available when a foreground is selected."

It also says "A background cannot be used with a Power Point foreground."

You'll want to use the auto advance settings in the foreground section of the cue editor.  Right above the cue auto advance settings.
