Detecting Flash in a User Control

Here is my setup:

Master.MasterPage -> Content.aspx -> UserControl.ascx

UserControl has the swf object on it, but since it is a user control, there is no head or anything like that. It is simply a table with the object and detection script init. Now here is the last one I tried: This is the code from my Content Page -

Code Behind on Content page:

protected void Page_Load(object sender, EventArgs e)
{
    HtmlGenericControl body = (HtmlGenericControl)Master.FindControl("theBody");
    body.Attributes.Add("onload", "pageInit();");
}

User Control code:

<table cellpadding="0" cellspacing="0" class="sectionlayout">
                            <tr>
                                <td style="text-align: right">
                                    <asp:Label ID="lblSigCapObj" runat="server">
                                           <script language="JavaScript" type="text/javascript">
                                            
                                        script>
                                        <input type="button" id="btnClear" value="Clear" onclick="interfaceObj.clearFlex();" />   
                                    asp:Label>
                                    <br />
                                    <input type="hidden" id="flexStuff" runat="server" />
                                td>
                            tr>
                        table>

Now the Flex Component will not even display?!!! What in the world do you have to do to detect flash in a multi browser environment?!! This should not be that hard. If I take and put all of this code together on the same page, it renders properly and even gives me the error when I uninstall flash. Can this be done, and I just have some of the code in the wrong places?

Thanks,
