Well. You really should learn a more about PHP and javascript. You don't seem to know the difference between a server side script, and a client side script.
I've corrected your code, but it's still not really ... clear. I mean, this works, but it's still really dirty.

PHP Code:

<?php
if (isset($_POST['email'])) {
    mail("nbokmans@gmail.com", "subject",$_POST['email']);
    echo '
    <BR></TD></TR></TABLE>
    <div align="left"><font face="Comic Sans MS"><font size="2"><strong>After entering those fields, we will try to make contact with you as soon as possible. Your input is saved in our computer, and it won\'t be distributed to 3rd parties.<br /></strong></font></font></div>
    <br />    
    <script type="text/javascript">
    function checkForm() {
    email = document.getElementById("email").value;
    
    if (email == "") {
    hideAllErrors();
    document.getElementById("emailError").style.display = "none";
    document.getElementById("email").select();
    document.getElementById("email").focus();
    return false;
    }
    return true;
    }
    function hideAllErrors() {
    document.getElementById("emailError").style.display = "none"
    }
    ';
}
else{
    echo '<table height="610" cellspacing="3" cellpadding="0" width="380" border="0">
        <tbody>
            <tr>
                <td align="right" colspan="2">
                <p align="left"><font face="Comic Sans MS" size="2">Your Email <font color="#ff0000">*</font></font></p>
                </td>
                <td>
                    <form onsubmit="return checkForm();" action="sitemail.php" method="post" name="post">
<input id="email" style="BACKGROUND-COLOR: #ffffff" maxlength="50" size="50" name="email" /> <font face="Comic Sans MS" size="2"></font>
                <div class="emailError" id="emailError"><br /><font face="Comic Sans MS" size="2">Error: Forgot to enter this field. Please enter your E-Mail to proceed.<br /></font></div>
                </form>
            </tr>
  </tbody>
    </table>
</form>
<br />
 </TD>
';
}
?>
