I posted a self contained HTML file that you can use anywhere - inside or outside of QuickBase. What the file demonstrates is that you can read the csv out of a file selected through a file control and log the csv to the console. To see the console output press F12 in any modern browser. The demo stops there. You have to do something further with the CSV other than log it to the console to make the example useful. If you are new to script you should learn how to use the JavaScript console as it will be your greatest aide in debugging and developing script.
