I've received some great help here and I made a couple
macros and assigned them to a button on the toolbar. They
work great in the file I wrote them in.

When I open another existing spreadsheet, the buttons are
there, but the macros aren't, so I get an error.

How do I make those macros available to all documents,
both existing and future? Similar to how Word's
normal.dot template works.

Thanks in advance.
