Hey Flexers I am having trouble creating a function that would total all the items added to my shopping cart. If anybody can help me out with my code, I'd appreciate it. I am still new to flex and don't know much of actionscript 3 so any advice would help me out alot. Below is a link to the shopping cart app(right click if you want to view the source) and the code below it, is the code of my shopping cart which has the calculateTotal() function that I tried to do to calculate the added items.
