PHP Syntax Help

The following piece of validation code is almost correct.  However, I don't know how to write the "IF" part:
	$trimmed = array_map('trim', $_POST);
	
	$$un = $ue  = . if(isset($_POST['team_join']) && $_POST['team_join'] != "Create New Team") {echo $goal_amount .'==';})FALSE;
	
	// Check for a user login:
		if (preg_match ('/^[A-Z a-z 0-9\'.-]{2,40}$/i', $trimmed['user_login'])) {
			$un = $trimmed['user_login'];
		} else {
				echo '<p class="error">Please enter a username!</p>';
		}

		
	// Check for a Email:
	if (preg_match ('/^[\w.-]+@[\w.-]+\.[A-Za-z]{2,65}$/', $trimmed['user_email'])) {
		$ue = $trimmed['user_email'];
	} else {
		echo '<p class="error">Please enter a valid email address!</p>';
	}

	// Check for a Goal Amount:
	if(isset($_POST['team_join']) && $_POST['team_join'] != "Create New Team") {
		if(isset($_POST['goal_amount'])) {
			$goal_amount = $_POST['goal_amount'];
		} else {
			echo '<p class="error">You must unter a goal amount!';
		}
	}	

//  START IF EVERYTHING IS VALID
			
if ($un && $ue . if(isset($_POST['team_join']) && $_POST['team_join'] != "Create New Team") {echo '&&'. $goal_amount;}) {

BLAH BLAH BLAH
 }

I've no idea what you are trying to do but at a guess

if (isset($un) && isset($ue) && isset($_POST['team_join']) && $_POST['team_join'] != "Create New Team") {echo '&&'. $goal_amount;}
