You are now creating the master poll template for your poll.
The text of the page has been pre-loaded with the template substitution that you will need but there are some fine adjustments that must be made manually. Follow the instructions contained in the comments (surrounded by <!-- and -->) to finish creating your template.
The poll's expiration time is coded using a clock that starts once you save this page—this is the reason for the substitutions in the last two (hidden) parameters. Do not modify them; to modify poll run length use expiry instead!
