Can't complete a purchase

I’ve been trying to purchase a new Razer Blade 18”, but when I get to the “Continue to Shipping button” (after the shipping and billing address screen, nothing happens. I click on it, nothing. No error message, no new screen. I’ve cleared my cache and done everything else I can think of on my end. Is anyone else having this problem? And does anyone have any suggestions as to how to get past this? TIA.
