Note I do not have xlsm, I am using LibreOffice Calc. When I open the xlsm file and try to draw a card, I get the following error:
BASIC syntax error.
Unexpected symbol: (.
This may be unique to LibreOffice, however.
I've done a little research and LibreOffice doesn't implement VBA in quite the same way as Excel, which I'm guessing is the problem. In theory I could grab a copy of LibreOffice and work something out, but in practice I have eleventy-billion things to do until mid-January so it's unlikely I'll get to that soon, if ever.
