i have made everything as i was supposed to, but with the new cart display, when i delete a product with a checkbox, it deletes products that are under it. This happens for sure if for example there are four products in the cart. if you delete the second product, it also deletes the products under it.
You can see the page at: index.php and make some tests.
I noticed that the code e-cart generated for the checkbox is different from the one in powerstore.
Do you have any suggestions?
