WooCommerce Variation Not Able to Add to Cart on Mobile Device

On a laptop, an option (variation) can be selected and added to the cart that is on this WooCommerce Product page. On a mobile device, after the option is selected and then “add to cart” selected it gives the message “Please select some product options before adding this product to your cart.” There does not seem to be a way to actually make the selection so it can be added to the cart. Please HELP. I need this fixed in the next three days. I have the Alante Grid theme.
