Nope, your macro is underquoted so the # is treated as a comment as the
macro expansion stack unwinds.

Add more quotes!  I haven't tested this, but something more like this
should give you more success:

define(`QuoteVariable',
`ifelse(`substr(`$1', 0, 1)', `i', `#$1',
  `ifelse(`substr(`$1', 0, 1)', `o', `#$1', `"$1"')')')

However, you could do the same thing much more easily with the patsubst
macro (if you quote it correctly!).

Cheers,
        Gary.
