So I just inserted a flash object into my dreamweaver page. 

The flash works fine the direct link here works: http://www.abbottsports.com/tennis/flash/tennismenu.swf

But when you visit the page: http://abbottsports.com/tennis/adulttennis.php

it's just blank space.

Here is my flash code:

<object id="FlashID2" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="597" height="115">

        <param name="movie" value="flash/tennismenu.swf" />

        <param name="quality" value="high" />

        <param name="wmode" value="opaque" />

        <param name="swfversion" value="15.0.0.0" />

        <!-- This param tag prompts users with Flash Player 6.0 r65 and higher to download the latest version of Flash Player. Delete it if you don’t want users to see the prompt. -->

        <param name="expressinstall" value="/htdocs/Scripts/expressInstall.swf" />

        <!-- Next object tag is for non-IE browsers. So hide it from IE using IECC. -->

        <!--[if !IE]>-->

        <object type="application/x-shockwave-flash" data="flash/tennismenu.swf" width="597" height="115">

          <!--<![endif]-->

          <param name="quality" value="high" />

          <param name="wmode" value="opaque" />

          <param name="swfversion" value="15.0.0.0" />

          <param name="expressinstall" value="/htdocs/Scripts/expressInstall.swf" />

          <!-- The browser displays the following alternative content for users with Flash Player 6.0 and older. -->

          <div>

            <h4>Content on this page requires a newer version of Adobe Flash Player.</h4>

            <p><a href="http://www.adobe.com/go/getflashplayer"><img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.g if" alt="Get Adobe Flash player" width="112" height="33" /></a></p>

          </div>

          <!--[if !IE]>-->

        </object>

        <!--<![endif]-->

      </object>
