I feel so dumb!
I have this expession attached to a table: (org-lookup-all $1
'(remote(payments,@2$4..@>$4)) '(remote(payments,@2$2..@>$2)))
It is returning the right list of numbers since I can examine them with
(nth n ....
How do I add the list up? I keep getting #ERROR or obviously wrong
answers. What I want is something like
$2='(apply '+ (org-lookup-all $1 '(remote(payments,@2$4..@>$4))
'(remote(payments,@2$2..@>$2))))
but that gives me errors since (I presume) the list is a bunch of strings.
Thanks for any help,
Alan

If they *are* a bunch of strings, then mapping string-to-number across the
list should do the trick:
$2='(apply '+ (mapcar (function string-to-number) (org-lookup-all $1 '(remote(payments,@2$4..@>$4)) '(remote(payments,@2$2..@>$2)))))

That worked a treat - thanks Nick.
