This is not the problem here.
The syntax here would be $[desk.name$$d] or better yet (in 2.5.6+)
$[desk.name$[desk.n]], note a single dollar is enough here.
The problem is that nothing inside $[] is expanded, i.e. you can't
nest variables. You hovewer may do currently the following:
# be careful about shell escaping, there are extreme conditions
DestroyFunc ExpandAndRun
AddToFunc ExpandAndRun
+ I PipeRead `echo '$*'`
DestroyFunc DynMenu
AddToFunc DynMenu
+ I ExpandAndRun Popup Menu$$$$[desk.name$[desk.n]]
The plus command converts $$ to $, so ExpandAndRun and shell actually
get only 2 dollars and $[desk.n] is already expanded. Then PipeRead
expands the resulting $[desk.name3].
=--=
This is not the first message about nesting variables, so one option is
to introduce a new command (or prefix if you like) Expand for this.
DestroyFunc DynMenu
AddToFunc DynMenu
+ I Expand Popup Menu$$$$[desk.name$[desk.n]]
Another option is to fix the expanding, so the inner $[] is expanded,
in this case only 2 dollars will be needed. And the third option is to
implement nested variable expansion, in this case one dollar will work
and no additional commands will be needed.
I will do the second option and then either the first or the third.

Mikhael.
