Javascript to Flash

[mark-ids]

Hi all

I hope you can help.
I've got a video in a .swf file which starts paused (autoplay false), but I need to restart it using javascript. Here is the code:

AS3:

import flash.external.ExternalInterface;
function playMyVideo():void
{
 video.play();//where video is the name of the video component
}

Javascript:

function getFlashMovie(movieName) {
  var isIE = navigator.appName.indexOf("Microsoft") != -1;
  return (isIE) ? window[movieName] : document[movieName];
}

function callToActionscript() 
{
 getFlashMovie("clip1").playMyVideo(); 
}

HTML:

<div class="bluebox" id="video">
			<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="616" height="450" name="clip1" id="clip1" align="middle">
				<param name="movie" value="../hazard/1.swf" />
				<param name="quality" value="high" />
				<param name="bgcolor" value="#000000" />
				<param name="play" value="true" />
				<param name="loop" value="false" />
				<param name="wmode" value="window" />
				<param name="scale" value="showall" />
				<param name="menu" value="true" />
				<param name="devicefont" value="false" />
				<param name="salign" value="" />
				<param name="allowScriptAccess" value="always" />
				<!--[if !IE]>-->
				<object id="clip1" name="clip1" type="application/x-shockwave-flash" data="../hazard/1.swf" width="616" height="450">
					<param name="movie" value="../hazard/1.swf" />
					<param name="quality" value="high" />
					<param name="bgcolor" value="#000000" />
					<param name="play" value="false" />
					<param name="loop" value="false" />
					<param name="wmode" value="window" />
					<param name="scale" value="showall" />
					<param name="menu" value="true" />
					<param name="devicefont" value="false" />
					<param name="salign" value="" />
					<param name="allowScriptAccess" value="always" />
				<!--<![endif]-->
					<a href="http://www.adobe.com/go/getflash">
						<img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash player" />
					</a>
				<!--[if !IE]>-->
				</object>
				<!--<![endif]-->
			</object>
</div>
<a href="#" onClick="callToActionscript();">Click me!</a><br>

For some reason I keep getting the

getFlashMovie("clip1").playMyVideo is not a function

It seems so simple, but I can't see where its going wrong.
