Answer 1

You really need to set the message before you try to output it.

Answer 2

To elaborate on David's answer: move the PHP block before the form markup, like so:
<?php
if(isset($_POST['submited'])) {
$RFname = $_POST['RFname'];
$RLname = $_POST['RLname'];
$USERname = $_POST['UserName'];
$USERpassword = $_POST['UserPass'];
$USERemail = $_POST['UserEmail'];
$USERwebsite = $_POST['WebSite'];
$check=$db->query("select 1 from loginaccess where Email ='".$USERemail."'");
if(mysqli_num_rows($check) > 0 ) {
$msg = "<span style='color:#F00; font-size:14px; font-weight:bold;'>This email already taken</span>";
}
?>
<form action="<?php $_SERVER['PHP_SELF']; ?>" method="post">
<table width="300" border="0">
<tr>
<td colspan="2"><?php print($msg); ?></td>
</tr>
<tr>
<td> *First name</td>
<td><span id="sprytextfield3">
<input type="text" value="" name="RFname" />
<br>
<span class="textfieldRequiredMsg">A value is required.</span></span></td>
</tr>
<tr>
<td>*Last name</td>
<td><span id="sprytextfield4">
<input type="text" value="" name="RLname" />
<br>
<span class="textfieldRequiredMsg">A value is required.</span></span></td>
</tr>
<tr>
<td>*User name</td>
<td><span id="sprytextfield1">
<input type="text" name="UserName" value="" />
<br />
<span class="textfieldRequiredMsg">A value is required.</span></span></td>
</tr>
<tr>
<td>*Password</td>
<td><span id="sprypassword1">
<input type="password" name="UserPass" value="" />
<span class="passwordRequiredMsg"><br />
A value is required.</span></span></td>
</tr>
<tr>
<td>*Email</td>
<td><span id="sprytextfield2">
<input type="text" name="UserEmail" value="" />
<br />
<span class="textfieldRequiredMsg">A value is required.</span><span class="textfieldInvalidFormatMsg">Invalid format.</span></span></td>
</tr>
<tr>
<td>Web site</td>
<td><input type="text" name="WebSite" value="" /></td>
</tr>
<tr>
<td> </td>
<td><input name="submited" type="submit" onClick="MM_swapImage('Image1','','images/blog.png',1)" value="Register"/></td>
</tr>
</table>
</form>
