Hello,
I'm sorry but it's difficult to understand your message ; specially without any context, screenshot or context.
It looks like you created a link to the customer cart and you want in fact a link to the checkout.
Because we don't know anything about that "cart icon" and how you create it ; please understand that it is currently impossible for us to guide you because we don't know what you currently have.
Regards,

By the way, do not send me private message, use the "contact us" form instead.
