Current Cart total on single product page

Hi,

I am new to Shopify and just settting up my first store. I am useing Sense theme and want to be able to display a current spend total on the single product page, near the buy buttons.

As the store is set up at the moment, there is no way for customers to see there total cart cost unless they click on the cart or addd soemthing to the cart so the cart drop down shows. I know through my own experiences that this is anoying and people like to be able to see there total spend so far, without having to go to the cart.

I have sent a screenshot of my current test set up but its very ugly and the discount code/sub total/est total is an add on ap and also doesnt update properly. I would like to find a way to show customers current basket total on the single product page?

Thanks in advance if anyoine can advise on this!
