Michelle,
Instructions on how to embed a pdf from Google Drive can be found here: http://www.alicekeeler.com/2016/06/05/google-drive-embed-pdf/
Once you do that, in Weebly, insert an "Embed Code" element where you want the pdf to be, then paste in what you copied from Google Drive.
Then, when you make a change in the rules, the embedded pdf is automatically updated so long as the pdf link and name stays the same in Google Drive. If not, then step one will have to be repeated to update the embedded code's link.
