I made Modules with sub routines (not functions) that I wanted to share among many workstations on the network. I saved it as .xla. I added the .xla to my add-ins but none of the macros I wrote show up in Macros viewer (Tools->Macros-> Macros...)

In VB Editor I can see the modules and the sub routines I wrote.

I am really confused how to make Excel work in a multi-user environment and how to share Code among workbooks in a multi-user environment. I wanted to tie the sub routines I made in the .xla to a custom tool bar. When I open the tool bar I don't want the original workbook in which I created the toolbar and it's subroutines to open.

Really confused about excel multi-user. It almost seems like Excel is not made for multi-user.
