// 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
