Resolved PowerPoint 2007 Start Slide Show From Current Slide doesn't work

My daughter is doing school project with PowerPoint 2007.

It's fine until slide #17, then two problems came up:

Problem 1. While editing slide #17, she wanted to preview the animation effect from this slide onward. However, the slide show started from the 1st slide, no matter she clicked the Slide Show button, or clicked the "From Current Slide" button from the Slide Show ribbon. What's wrong?

Problem 2. Anywhere on slide #17, after animation completed, a mouse click would bring up the slide #3, instead of slide #18? What's wrong?

Please help. The assignment deadline is tomorrow.

 

Problem resolved.
At Slide Show > Set Up Slide Show, under Show type, set the Show slides to All.
