Tony,
Does Option Private Module do what you need ?

I have written an addin which amongst other things has some custom
functions
available for general use (under the User Defined Category) once the addin
is installed.

However, I also have some functions I would only like available for use by
my VBA code. Is there any way I can make these functions "publically
available" to all of my code, but NOT appearing in the Excel Insert
Function
list.

Thanks
