'Buy Now' option does not work on Chrome.

[PICES]

Recently I launched my website via Google Sites.

On my website do I have merchandise, the problem is that customers can't order merchandise on every browser except Safari.

Does anyone know how to fix this? I used the 'Buy Now' option for transactions.

This is the link to my store: https://sites.google.com/view/pices/store

Thanks,

Kind regards,
