I have a HTML page.
It has a table that shows a list of items that you can buy.
It has 3 columsn (item name, item price, last column is a drop down box for quantity).
I want to have below the table "Total: $0.00". I want this to automatically update each time the drop down box is changed next to an item. For example if row 1's item was $12.00 and item quantity was changed from default of 0 to 2 then that total text should auto-update to $24.00.
