Fix OR implement a new currency convertor tool for my website + move search bar

Website is hosted on SHOPIFY Task 1: Currency Converter I have a currency converter tool coded into my website which allows customers to browse in 5 different currencies (although the checkout will always charge in AUD). It used to work fine, but recently it doesn't convert the dollar amount it only changes the currency. For example. AUD$60 becomes USD$60 instead of changing it to USD$46(approx). It works if you refresh the page, however, most customers will not know to do this. I need someone to fix this error or code a new convertor. Adding a paid app is not a suitable fix. Task 2. The Search bar is centred and I simply want it sit to the right. This should be a quick fix for those experienced with HTML. I would like this task to be completed within 24hours once the job has been assigned. Please quote "onto it" in your offer so I know you have read the whole project. We are looking for a developer on an ongoing basis if this task is successful. Thank you
