That is because the scope is restricted to the module that the private
procedure is within.

To make it available to another module it must be Public. You can have the
procedures public but private to the project (that is not accessible from
another project, and not in the macros list in Excel), by making the
procedure public and by adding the phrase Option Private Module to the
module declarations at the start.

Thanks in advance.
