Darwin: This is probably specific to a certain page in the section you are running it on. You can isolate the page by running the macro on a section with a single page in it. You can do that for each page in the section. Once you find the page, send a copy of your page to support@getonetastic.com to troubleshoot.

I get "The page object does not exist." when running this macro.
