Boa tarde, sou iniciante em java, e estou aqui com um problema, tenho o player funcionando e a escolha dos videos também, eis o meu problema, o botão de "Prev & Next" não consigo por a mudar de video :/

div.section {
margin-bottom: 18px;

</style>
</head>
<body>
<div class="section">

O teu código tem uma indentação complicada...

Eu n sei se no original está bem indentado mas o que poseste aqui não tem indentação.

Tenta copiar e colar outra vez mas não uses o sistema para colar código (o botão <>). Digamos que está avariado.

Há um atributo na tag que te permite isso ou fazes tu um.
