I am creating a currency converter that not only converts the currency it also adds the total amount converted together and displays it in US$. My problem is that when I enter an amount to be converted it adds it to my total converted box, but when I add another amount to be converted it replaces the first amount instead of adding them together. How can I fix this? Also, when I close the application I lose all the previous data. How can I save this? I've have heard "SaveSetting" but I don't know how to use it.
Thanks!!!
