// CART REVISIONS
/*        Cart version 1.04

        10/05/02        - popupConvert() altered to let user choose currency if they click the
                                  "curreny convertor" link, not the "check todays rate" links

                                - Using images instead of wingdings font
                                  (there's no point keeping it - Kids, wingdings are bad, mmkay?)

                                - VAT Floating point error sorted (again)

                                 was using-
                                         vatcost = (priceFormat(vatcost)*quant);
                                 now using-
                                         vatcost = (priceFormat(vatcost)*quant);
                                         vatcost = priceFormat(vatcost);

        21/12/01        - popupConvert() altered to accomodate different currencies
                                  now pass popupConvert([cur]), cur can be any valid 3 letter
                                  currency code eg; 'USD' or 'EUR'

                                - Currency conversion rates are now able to cope with non-decimal
                                  values, I simply priceFormatted it!!

        29/11/01         - Floating point error on calculating VAT resolved
                                                (VAT now calculated before quantity applied)
                                UPDATE To Above: This didn't work, see 10/05/02 note above

                                - Can no longer select a delivery location until cart is loaded

                                - Rounding error on summing is corrected

        27/11/01         - Define font colors for the cart to contrast with the stripes
