Well, I am still new to Flex so I'm having trouble understanding what you all are saying. However, below is a link that has my app online so you get an idea of what is going into the cart (just right click to view the source). Now, I created a form below the datagrid that totals all my items when they are dropped in the cart. I receive no errors when saved, but when I run the app, it returns "NaN" in the label of the form. Why would this occur and what approach do I need to take to correct this error? Thanks for listening.
