Duvida com Lgin

[Wélita]

Olá Pessol estou começando a conhecer php e to precisando de algumas dicas.

Bem desenvolvi uma aplicação simples com login e senha, usando o dreamweaver e mysql.

Criei um formulario dentro desse form eu inseri 2 textfield um para login e outro para senha, inseri tambem um botao chamado entrar.

O problema e que quando clico no botão Entrar simplesmente da um erro, ou seja, não sou direcionada para a pagina de sucesso.

Lembrando que os usuario foram cadastrados com uso do phpmyadmin na tabela previamente criada.

Se alguém puder dar uma ajuda sera muito util.
