Validation of a HTML form

hello,
I have put this in my html form
</head>
<script language=“javascript”>
function docElem(elem){
return document.getElementById(elem);
}

        function checkTerms(){             
          if (docElem("cbTerms").checked == false){
               docElem("termsMsg").innerHTML = "You have to agree with the terms and conditions";                  
          }else{
               docElem("termsMsg").innerHTML = "";
               docElem("frmTerms").submit();
          }
      }
    &lt;/script&gt;

<title>

<form name=“postanadd” method=“post” action=“handle_form.php” id=“frmTerms”><div id=“termsMsg”></div>
[COLOR=Red]
Is this correct?

[COLOR=Black]
<input type=“checkbox” name=“cbTerms” id=“cbTerms” value=“off”>

<input type=“submit” onclick=“checkTerms();” name=“formSubmit” value=“Submit” id=“Submit2”>
