Some issues with the plugin

Hi,

based on the description and screenshots your plugin would be the best option for our charity campaign. We sell accesses to city exploration games and would like to donate schools.

Once our customers add the product to the basket they are instantly directed to the Checkout page by a code snippet added to the functions.php.

When I tested the plugin on the Checkout page I experienced the following. Selected the amount of 2000, clicked on Add Donation and on the Checouk summar the cart total swiches to zero and also Donation?x?1 is displayed as zero, so car total is zero.

The other issue is that however I set the donation product (#7316) to hidden in the catalog settings it is still displayed on the front end.

I hope there’s an easy solution to these.

Thanks
