you need learn better syntax: thau's javascript tutorial (beware it's little outdated)
you don't need [0] if stock, changenet, , lastsale not arrays. if arrays should put var when define array first time.
without using arrays:
var stock = "cisco", changenet = "0.155 0.72%", lastsale = 21.775; //amount in dollars document.write("stock: " + stock + ", changenet: " + changenet + ", last sale: " + lastsale); with using arrays:
var stock = [], changenet = [], lastsale = []; stock[0] = "cisco"; changenet[0] = "0.155 0.72%"; lastsale[0] = 21.755; document.write("stock: " + stock[0] + ", changenet: " + changenet[0] + ", last sale: " + lastsale[0]); if plan calculations recommend doing else changenet variable, making 2 different variables, 1 decimal number, , 1 perentage.
