SWF problem on SWFObject 1.4

[Guest]

okey i am using SWFObject v1.4.4. My question is why when i put 100% widht in my properties it doesnt work?

   <div id="flashcontent1">

<h1>To see this content you need to have installed Flash Player v9. Download it from

  <a href="http://www.adobe.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash" target="_blank"><b>here</b></a>.</h1>

   </div>

<script type="text/javascript">

var so = new SWFObject("flash/main_header.swf", "header1", "100%", "425", "9", "#000000");

so.addParam("menu", "f");

so.write("flashcontent1");

            </script>

it works on SWFobject 2.0 of course with dif syntax:

   <div id="flashcontent1">

<h1>To see this content you need to have installed Flash Player v9. Download it from

  <a href="http://www.adobe.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash" target="_blank"><b>here</b></a>.</h1>

   </div>

<script type="text/javascript">

// <![CDATA]

var flashvars = {};

var params = {};

params.align = "middle";

params.bgcolor = "#000000";

params.allowfullscreen = true;

var attributes = {};

attributes.id = "flash";

attributes.name = "flash";

swfobject.embedSWF("flash/main_header.swf", "flashcontent1", "100%", "100%", "9.0.45","swfobject/expressInstall.swf", flashvars, params, attributes);

// ]]>

</script>
