I have a wiki with several pages in the page tree that each have their own spreadsheet embedded on the page. These spreadsheets are user uploaded and contain numerical data. For example page A has a spreadsheet with a value of 12, page B has a value of 10, etc.
I would like to total up all the values of the individual pages and display the total on the home page. Is there a way to automatically pass spreadsheet data between pages? So if page A has 12 and page B has 10, I would like the homepage to display 22.
Thanks for the help!
