[Resolved] [Resolved] Function not returning value

[Terminator]

Probably something easy, but I dunno understand. So any help is appriciated.

I have this function (functions.php):

function checkuser($tUsername, $tPassword) {
	require('./admin/configforum.php'); //database configuration

$con_user= mysql_connect($host,$user,$pass) or die(mysql_error()); 
mysql_select_db($db);

$queryuser = "SELECT * FROM user WHERE username='$tUsername' AND password=MD5(CONCAT(MD5('$tPassword'), salt))";

$resultuser = mysql_query($queryuser);
if (mysql_num_rows($resultuser) == 0) {
	$usercheck = "invalid";
}
else {
	$objuser = mysql_fetch_object($resultuser);
	$usercheck = "valid";
}
echo "$usercheck  ";	
mysql_close ($con_user); //close user connection
return $usercheck;
}

And I have the following PHP code in comment.php

<?
				if (isset($_POST['action']) && $_POST['action'] == 'postcomment') {
					require('./admin/functions.php');

				$username = $_POST['tUsername'];
				$password = $_POST['tPassword'];
				$comment = $_POST['Tcomment'];
				$newsid = $_GET['newsid'];

				checkuser($username ,$password);
				if ($$usercheck == 'valid') {
					echo $usercheck;
					insertcomment($comment,$newsid,$objuser->username,$objuser->userid);
					echo "<script>setTimeout('window.close()',1000)</script>";	
				}
				else {
					echo $usercheck;
					echo "Invalid username or password, please try again";
				}

			}
		?>

Now in comments.php the variable $usercheck = empty, but in functions.php it's containing valid or invalid.

So my question is, how do I get the value of variable $usercheck into comment.php

(probably a stupid error from the user 😉 )

You haven't assigned the result of checkuser() to a variable

$usercheck = checkuser($username ,$password);
