OK, I got my previous issue resolved by installing the updated beta version of Spreadsheet that allows apostrophes and quotation marks.
Everything was looking perfect, so I installed the export modules grid-excel.php and grid-pdf.php. I followed the instructions, and the modules work by opening a PDF or offering an xls sheet to download.
The problem is both sheets are empty, as if they were loading a blank sheet, or the demo sheet or something.
How can I get my saved sheet to be the one that is exported?
