<?php

$rand = mt_rand(0,20);

{
$submit = $_post["number_accepted"];

if ($submit > 20 || $number_accepted < 0) {
echo "guess should be between 0 and 20";
}

elseif ($number_accepted > $rand) 
{
echo "guess to high";
}
elseif ($number_accepted < $rand)
{
echo "guess too low";
}
else
 {
echo "congratulations <?php echo $_post["firstname"]'.'["lastname"] ?>"

Not clear what not working. Couple of suggestion

1. I think the _POST keyword is case sensitive, replace _post with _POST
2. $number_accepted, not clear where it being declared, maybe $submit should be $number_accepted?
3. look like there some syntax error at the else statement.

PHP

<?php

$rand = mt_rand(0,20);
if (isset($_POST["number_accepted"])) 
{
	$number_accepted = $_POST["number_accepted"];

	if ($number_accepted > 20 || $number_accepted < 0) {
		echo "guess should be between 0 and 20 <br/>";
	}

	elseif ($number_accepted > $rand) 
	{
		echo "guess to high <br/>";
	}
		elseif ($number_accepted < $rand)
	{
		echo "guess too low <br/>";
	}
	 else
	 {
		echo "congratulations " .  $_POST["firstname"] . ' ' . $_POST["lastname"];
	 }
}

?>
