Can anybody help me set this code into an array?

Thanks, can you help me understand how to make an array work?

I need to fade toggle a different country png for each country button and fade out the rest of the country images i.e.: when i click the UK button i need to fade toggle the UK png and fade out the other countries

when i click the USA button i need to fade toggle the USA ing and fade out the other countries and so on

sym.getSymbol("Countries").$("UK").fadeToggle();sym.getSymbol("Countries").$("USA","AUS","Hongkong","Switzerland","Ireland","Indias","Japa n","Netherlands","Spain").fadeOut();

sym.getSymbol("Countries").$("USA").fadeToggle();sym.getSymbol("Countries").$("UK","AUS","Hongkong","Switzerland","Ireland","Indias","Japan ","Netherlands","Spain").fadeOut();

etc

but it doesn't seem to work how i have it and i have been told to do an array but I'm not sure how?
