[Java+PHP] Select options and onChange.

[xFalcon]

Well I'm trying to make a script for my website that show a text when player choose an option on a select tag.
Here is what I did but cant get it working >.<

<?php
	echo '<table>
			<tr>
				<td>	<center><b>Select your region:</b></center>	</td>
				<td>	<select name="reg" id="reg" onChange="alter();">
							<option value="">-----------</option>
							<option value="EU">EUROPE</option>
							<option value="CH">CHINA</option>
						</select>
				</td>
			</tr>
		</table>
		<br />
		<div id="CH" style="display:none">hi china</div><br />
		<div id="EU" style="display:none">hi europe</div>';		
?>

Here is my javascript function..

function alter() {							
if(document.getElementById('reg').value == "CH") {document.getElementById('CH').display = ""; document.getElementById('EU').display = "none";};
if(document.getElementById('reg').value == "EU") {document.getElementById('EU').display = ""; document.getElementById('CH').display = "none";};
}

                        </select>
                </td>
            </tr>
        </table>
        <br />
        <div id="CH" style="display:none">hi china</div>
        <div id="EU" style="display:none">hi europe</div>';
?>

function updateL() {    
    var valL = document.getElementById('reg').options[document.getElementById('reg').selectedIndex].value;
    
    if(valL == "CH") {document.getElementById('CH').style.display = "";document.getElementById('EU').style.display = "none";}
    if(valL == "EU") {document.getElementById('EU').style.display = "";document.getElementById('CH').style.display = "none";}
}

Yesterday I could get it working thanks anyways :] I'm having this other problem though.. Here is my code:

if(!isset($_REQUEST['action']) or ($_REQUEST['action'] != 'final')) {
	echo '<form action="?page=form&action=final" method="post" name="form">
		<table cellspacing=15 width="80%">
			<tr>
				<td>	<center><b>Select your Region:</b></center>	</td>
				<td>	<select name="reg" id="reg" onChange="alterreg();" style="width:150px">
							<option></option>
							<option value="EU">Europe</option>
							<option value="CH">China</option>
						</select></center>
				</td>				
			</tr>
		</table>
		<input type="submit" id="enter" value="Process" style="display:none;width:150px"/>
		</form>
}
else {
	if(empty($_POST['reg'])) echo 'fill reg';
	else echo $_POST['reg'];
}

I want when player select CH or EU and click on buttom 'Process' I can get the value with $_POST['reg'].. but I'm always getting 'fill reg'.. like if it was always empty >.<
