CRE Loaded 6.2 Template Error & Updates Required

I would like bids to resolve the issues detailed below. 1.

The [login to view URL] file doesn't display the "£" (Great British Pounds) sign, merely a square. I would like it to display the correct currency. 3.?

In the Checkout Process, the section to enter a discount code doesn't exist, it merely states something like "TEXT_ENTER_GV_CODE", when it should say something like "Enter your discount coupon here". 5. In the search box in the centre of the page, when you enter a search term, the term/wording is displayed in white, when it should be black. Our website is [login to view URL]
