As long as the Adwords Account and the Google Docs account use the same login, it will be able to access any spreadsheet you have. I suggest opening my sample spreadsheet and then making a copy if it in your account. You can then replace the URL from the script below with the url of your copy of the spreadsheet.
Link to my sample spreadsheet: https://docs.google.com/spreadsheet/ccc?key=0Aotb6eheEOpodEhDM2hqQmhfeTdHT3BLMl80aDRxTkE
Thanks,
