Moved the file out of the root into a folder. Now it’s calling out an unsupported URL. I triple checked the path and the path it’s calling out (below) in the error message appears to be a proper path for Windows
`Message: Unsupported URL <file:///c:/Users/computer%20one/My%20Documents/Summary.ods>: "type detection failed".`
The space encoding %20 shouldn’t be a problem should it?
Also used a blank/fresh Summary.ods spreadsheet being copy/pasted to from the main.ods spreadsheet.
