Add To Cart Error

First of all, thank you for a wonderful product, extremely powerful yet at the same time simple to use. All the best to yor team

I am facing a problem with the 'Add to cart' button, both in the product display page and the module.

1. If the user is not logged in, and presses the Add to Cart button, there is a browser error...

The page isn't redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

This problem can sometimes be caused by disabling or refusing to accept
cookies.



2. If I then press the browser Back button, there are a lot of messages...

There is no propblem if the user is logged in.

Ideally, I would like the Add To Cart button to be visible only to logged in users. Is there any simple modification to show.php or any other file that to achieve this>

I can use the following code

$db =& JFactory::getDBO();
$user =& JFactory::getUser();
$loggedinuser = $user->id;

but where exactly do I put the condition

if ($loggedinuser == '0') {
....
}

I am using Joomla 1.5.23 and Hikashop Starter 1.5.4

Thanks

Thanks. I have applied the condition and the button now shows/displays as required
