Como impedir a gravação dos dados no banco de dados???

Boa tarde amigos, estou fazendo um Form que envia os dados para um banco de dados, pesquisei no forum e achei algo, ele funciona mas so da a mensagem de erro e grava mesmo assim no bd, sei que estou fazendo algo de errado, mas eu n sei como fazer ele funcionar direito!

Código q achei no forum!

If Request("nome")="" Or Request("cpf")="" ThenResponse.Write "Erro!!!"Else' Aqui vai sua rotina de inserçãoEnd If

a minha pagina de inserção de dados foi feita pelo dreamweaver!!

quero saber como usar o codigo acima no codigo "cansativo" abaixo!!
