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))

but that gives me errors since (I presume) the list is a bunch of strings.

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.
