Object tag not recognized inside form tag

Problem: When developing a page in ASP.NET, an object tag (<object>) is not recognized when it is placed in an HTML form tag (<form>).

e.g.
<html>
<head>
   <script type="text/javascript" language="javascript">
    function readScript()
    {
        Card.Connect();
    }
   </script>
</head>


 <body color=white>
    <form name="frmRead" id="frmRead">
        <object id="Card" name="Card" classid="abcDll.dll#abcDll.Card" style="display:none" ></object>
        <input type=button value="Read Card" onClick="readScript();"></td>
    </form>
 </body>
</html>

Solution: Inside the <form> tag, <object> element is out of scope. Instead of directly calling the id of the object, get the id using javascript.
function readScript()
    {
        var cardObj = document.getElementById("Card");
        cardObj.Connect();
    }

Special thanks to StackOverFlow :D
