Security :: Login Using Database User Table

I am dtrugling with the log in of .net. I have studied a wrox asp.net 2 book and it says add

<authentication mode="Forms">
<forms name="Wrox" loginUrl="Login.aspx" path ="/" />
</authentication>
<authorization>
<deny users ="*" />
</authorization>

to the web.config file. This automaticaly sends me to Login.aspx. The problem I have is I have added this line to the code behind in Login.aspx

protected void submit1_Click(object sender, EventArgs e)
{
FormsAuthentication.RedirectFromLoginPage(User.Text, false);
}

NOW this does not check the password but it should in THEARY send me to the page I was going to. It dosnt it stays on the login page.
