I am trying to insert a parameter through an aspx page via text box. I set my parameters up, but evertime I executenonquery, the @Username shows up in the database instead of the actual value. Below is my code. Can anyone shed a little insight?

            SqlParameter @UserName = new SqlParameter("@UserName", System.Data.SqlDbType.VarChar);
            @UserName.Direction = ParameterDirection.Input;
            @UserName.Value = txtUserName.Text;

cmd.Parameters.Add(@UserName);
