Mp4 video won't work

So sorry you're running into that, Sharon. I'm happy to lend a hand!

First, a few basics to cover:

• What version of Storyline 2 are you're using? To check, click the Help tab, then click About Storyline.
• If the options under the Insert tab are not working properly, a simple repair should help! Let us know if you're still having trouble after the repair, we'll keep digging!
