Sporadically for many years, I've sent out Google Forms using a mailmerge, and I've prefilled some questions with data from the Google Sheet I'm running it from. Input objects had the prefix "entry." and prefilling was as simple as using a link https://forms.google.com/1234abcd?entry.9876=Scott
However I've just created 4 forms, and none of them have an object named "entry.*". A search in the page source for "entry." comes up blank. How can I still prefill with my mailmerge?
