Please Help me,

The condition that prints to to the page telling the user that that the player type is available is not working. Please review my code below

var fullSquad = [ "Pogba", "Lukaku", "Sanchez", "Martial" , "Matic" ];

var search;

while(true) { search = prompt("Search for your favorite Manchester united player. Type List to see the list of all the players available or type quit to exit "); search = search.toLowerCase();
if (search === "quit" ) { break;

} else if (search ==="list") { alert(fullSquad.join(",")); } else { if (fullSquad.indexOf(search) > -1) { document.write("yes" + search + "is available for selection");

}else {

alert( search + " is not on the team"); }
}

}
