Liquid HTML simple correction on currency convertor

Hi there,

I have an online e-commerce store called curbwear com

I have installed buttons to show different curriences but am experiencing this problem:

1. Customer selects different currency then the default currency (so £ becomes €)

2. Prices are now shown in € on pages

3. When clicking on an individual product the prices revert to default currency (£)

4. if customer the selects their currency again (€), the symbol changes but the amount does not convert! So £26 becomes €26 and then if you click back on currency £, price is converted from € to £ (should be £ to €)

I am seeking someone to correct my coding to make the currency selection remain the same across all pages and to always recognise GBP as the default currency to convert from.

Finally, right aligning the currency buttons to the above cart button.

Store is hosted through Shopify.
