I have my code and it (sort of ) works.
First problem I have is it only adds the first item. It will not add more then one item also.
In other words it will only add the top information from the index.php file to the viewCart.php.
second problem - When i go to remove an item from the cart it works but it will take me negative and I dont want this
Below is my code- Thanks for all the help

echo"Connect Successful";
// Check connection
if (mysqli_connect_errno())
