You'll have to be more specific. I followed the procedure in your "How to use macros.txt" file.
Here is what my "Module1.xba" file looks like when I copy and paste the macro:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE script:module PUBLIC "-//OpenOffice.org//DTD OfficeDocument 1.0//EN" "module.dtd">

It still doesn't work.
