There really is no more Help than that. I seem to recall someone,
somewhere raving on about using the various Office platforms in
client-server relationships but don't recall the specifics. The
concept is simply that VBA is a common language across the platforms
and that the various platforms expose object libraries. Learn how to
program the target platform natively. Move that VBA code over to the
client platform, with appropriate object declarations and run it from
there.
In the issue that you've raised, create the VBA macros in Excel to do
exactly what you want. When that works properly, move the code over
to Access and make it work under program control.
