<?php
$user="beatrice";
$pswrd="bean";
$redirect=false;
$max_attempts=false;

$num_attempts=(isset($_POST["num_attempts"])) ? $_POST["num_attempts"] + 1 : 0;
$username = (isset($_POST["username"])) ? $_POST["username"]: "";
if(!isset($_POST["username"]))
{       $msg="Welcome to the Cameron Page!";
}else if($_POST["username"]==$user && $_POST["password"]==$pswrd)//everything matches, move to webpage
{       $redirect=true;
        $msg="";
}else if($num_attempts>10)//kicks user out of program
{       $msg="Exceeded the limit of tries.";
        $max_attempts=true;

From what I can tell, it looks as though you have a random php end tag "?>" there on line 42 that doesn't belong. If you clear that out, it might solve that error you're receiving.

IT looks to me like you didn't escape the double quotes, remember that when you have a double quote inside an echo you use \" instead of ". Also, in your code there are a few places where you used an ending ?> tag without the <?php at the beginning. Hope it helps

Alright, I just took what you originally had there for those lines and added the escapes like adyopo mentioned. You just missed a few with your second posting. For example, on line 4 (of your second post) you need quotation marks at the very end before the semi-colon. On lines 5 and 7 it appears you try to concatenate the values with the string, however you put the period, '.' only before the value. Take a look at the following, I think it should work...

<?php
	if ($max_attempts==false)
	{
		echo "<form action= " . $_SERVER["PHP_SELF"] . " method=\"POST\">";
		echo "User name :<br/><input type=\"text\" name=\"username\" value=\"" . $username . "\"><br /> ";
		echo "Password : <br/><input type=\"password\" name=\"password\" value=''><br />";
		echo "<input type=\"hidden\" name=\"num_attempts\" value=\"" . $num_attempts . "\">";
		echo "</p> \n";
		echo "<p><input type=\"submit\" value=\"submit your guess\"></p>";
	}
?>
