Linking to external documents

[Ealasaid A. Haas]

Hiya!

Here's what I'm looking to create: a Frame book which, when turned into 
a PDF, contains links that open external documents when clicked.

Seems simple, but I can't figure out how to do it.

Tricky bits:

- the links to the external docs need to be relative (ie, of the form 
Procedures/DDOC-00100-001.pdf rather than c:/My 
Documents/Report/Procedures/DDOC-00100-001.pdf) so that I can send a zip 
file containing the .pdf and its associated docs (which are held in 
subfolders) to other people.
- the external docs are in all sorts of formats -- .pdf, .tif, .doc, etc.

So far I've tried several of the options in Special>Hyertext with no 
luck (so far all the ones I try generate an error complaining that the 
doc in question doesn't exist and that I should make sure it's a Frame 
document ).

Thanks in advance for any help you can give me!

Cheers,
