Creating Play & Pause Buttons for Video

I’ve actually got a more frustrating question. I can get a video to jump to a specific point using the:
hypeDocument.getElementById('video1').currentTime = 0;
and then changing the 0, but I’m having trouble making it actually play from that point.
I’m using the video as a marker for other events happening on the timeline, so I can tee it up to also move to a specific point on the timeline by adding that other behaviour on click.
Have looked into this option (Sync animations to Video & Audio in Tumult Hype) but unfortunately all it does is play that specific moment on the timeline (but not the video) and then revert to the synced video/timeline as if playing straight.
Any help? Am I missing something here?
Thanks in advance.
