How to play video forwards and backwards using external push buttons?

Hello,

I am new to Adobe Animate, and tried to watch a bunch of tutorials and read instructions but simply couldn't get to what I want to do.

I would like to set up an interactive where there is a video people can control. Connected to the computer there will be two push buttons that users can interact with.

I would like one of the buttons to play the video forwards, and the other to play the video backwards. I haven't had success in how to set up this code, and keep getting error messages.

The error messages are usually something like "Scene 1, Layer 'Actions', Frame 1, Line 16, Column 2 1120: Access of undefined property Plate."
(I named my video "Plate" in the Library)

Here's the simple code I started with -

_________________________________

/* Click To Play Video (Requires FLVPlayback component)

Clicking on the symbol instance plays a video in the  specified FLVPlayback component instance.

Instructions:

1. Replace video_instance_name below with the instance name of the FLVPlayback component that you want to play the video.

   The specified instance of FLVPlayback video component on stage will play.

2. Make sure you have assigned a video source file in the properties of the FLVPlayback component instance.

*/

movieClip_1.addEventListener(MouseEvent.CLICK, fl_ClickToPlayVideo_2);

function fl_ClickToPlayVideo_2(event:MouseEvent):void

{

// Replace video_instance_name with the instance name of the video component

Plate.play();

}

_____________________________

Any direction, or even specific code could help.

Thanks,

Rachel
