Answer 1

Check your products table. In that table Retail_Price doesn't exit, so you are getting error.

Answer 2

Remove id column and it null value, assumed it is integer value and is auto_increment

    <?php 

                if(isset($_POST['insert']))
                {
                    echo $insert="insert into products (Product,Form,Strength,Generic_Name,Pack_Size,Retail_Price,Trade_Price) values
        ('".$_POST['Product']."','".$_POST['Form']."','".$_POST['Strength']."','".$_POST['Generic_Name']."','".$_POST['Pack_Size']."','".$_POST['Retail_Price']."','".$_POST['Trade_Price']."')";
                    $query_insert=mysql_query($insert);
                    if($query_insert)
                    {
                        $msg2="Inserted Successfully" or die(mysql_error());
                    }
                    else
                    {
                        $msg2="Product already exist";
                        echo mysql_error();
                    }
                }
            ?>

Answer 3

产品表中不存在Retail_Price字段，或者其拼写不同。
