I have a one dimensional array of data, but when the csv downloads, it's just a bunch of 0's instead of the text I set to be added to the array.
Run the project in Debug Mode (Shift+F4) and check the contents of your array.
Your event #16 on the screenshot runs on every tick, which is wrong. You need to move it as a sub-event to #17.
And the MIME type needs to be "text/plain" or "text/text", not "s".
But with 1D array you won't be able to send timestamps. I suggest using 2D array, or add question+answer+timestamp+newline to the string variable on every answer.
