[Orgmode] table formulas revisited

[Eddward DeVilla]

Hi all,

    This is something I thought I had working before.  In anycase,
anytime I use a range in a table, I cannot get it to evaluate.  It
dies before even reaching the formula debugger with "Wrong number of
arguments: #<subr mapconcat>, 2".  This is org 5.03 and I've tried it
on emacs 21.1.1 and 21.3.50.1.
    What's really weird is that I think this was working eariler this
week on the same version of org and emacs.  Can anyone else try
dropping this table in an org buffer and hitting C-cC-c on the TBLFM
line to confirm if it's just me?

Thanks,
Edd
