Multiple pieces of data can be delineated by commas and sent in a single line/request. Each 'save data' request will save to a new line in the .csv.
If the file exists, Kiosk Pro will add data to the existing file in a new line. Otherwise, a new file will be created. The filepath defined here (and in the function) is relative to the Kiosk Pro documents folder and should include the suffix '.csv'.
A local filepath using folders can be set here (for example, 'folder/test.csv'), but the folder must be manually created prior to running these functions. If you try to save to a folder that does not exist, the call will fail.
