Try in the VBE making a reference via tools/references, and checking the
xla.

I created an add-in (.xla extension) from a spreadsheet with quite a bit of
code. I have installed the add-in, and can see it from the Tools- Add-ins
dialog box. It also appears in the VBE Project Map.

However, I can not access the code except by associating it with a button
or
command menu. When I try to access it in code, I get a "Subroutine not
defined" type of message.

Am I doing something wrong, or is the only way to access the code via a
menu
command or button?
